Butterflies are part of the class of Insects in the order Lepidoptera. Moths are also included in this order. Adults butterflies have large, often brightly coloured wings, and conspicuous, fluttering flight. The group comprise the true butterflies (superfamily Papilionoidea), the skippers (superfamily Hesperioidea) and the moth-butterflies (superfamily Hedyloidea). Other families within Lepidoptera are referred to as moths. Butterfly fossils date to the mid Eocene epoch, 40–50 million years ago.[1]

Butterflies exhibit polymorphism, mimicry and aposematism. Some, like the Monarch, will migrate over long distances. Some butterflies have and parasitic relationships with organisms including protozoans, flies, ants, other invertebrates, and vertebrates. [2] [3] Some species are pests because in their larval stages they can damage domestic crops or trees; however, some species are agents of pollination of some plants, and caterpillars of a few butterflies (e.g., Harvesters) eat harmful insects. Culturally, butterflies are a popular motif in the visual and literary arts.

Snowflake obsidian 15 by James St. John

(~5.9 centimeters across at its widest)

-----------------------------------

Igneous rocks form by the cooling and crystallization of hot, molten rock (magma and lava). If this happens at or near the land surface, or on the seafloor, they are extrusive igneous rocks. If this happens deep underground, they are intrusive igneous rocks. Most igneous rocks have a crystalline texture, but some are clastic, vesicular, frothy, or glassy.

Obsidian is readily identifiable. It is a glassy-textured, extrusive igneous rock. Obsidian is natural glass - it lacks crystals, and therefore lacks minerals. Obsidian is typically black in color, but most obsidians have a felsic to intermediate chemistry. Felsic igneous rocks are generally light-colored, so a felsic obsidian seems a paradox. Mafic obsidians are scarce, but they are also black and glassy. Obsidian is sometimes referred to "glassy rhyolite".

Obsidian is an uncommon rock, but can be examined at several famous localities in America, such as Obsidian Cliff at the Yellowstone Hotspot (northwestern Wyoming, USA) and Big Obsidian Flow at the Newberry Volcano (central Oregon, USA).

Obsidian is moderately hard and has a conchoidal fracture (smooth and curved fracture surface), with sharp broken edges. Freshly-broken obsidian has the sharpest edges of any material known, natural or man-made (as seen under a scanning electron microscope).

Obsidian forms two ways: 1) very rapid cooling of lava, which prevents the formation of crystals; 2) cooling of high-viscosity lava, which prevents easy movement of atoms to form crystals. An example of obsidian that formed the first way is along the margins of basaltic lava flows at Kilaeua Volcano (Hawaii Hotspot, central Pacific Ocean). The obsidian sample seen here formed the second way.

Obsidian is unstable on geologic time scales - it will slowly convert to material that is not obsidian. A partially-converted obsidian is a distinctive rock called snowflake obsidian. The black portions of the rock seen here are rhyolitic obsidian (glass). The white patches ("snowflakes") are devitrification spots composed of cristobalite (SiO2, a polymorph of quartz).

Wikipedia (edited): "The common murre or common guillemot (Uria aalge) is a large auk. It has a circumpolar distribution, occurring in low-Arctic and boreal waters in the North Atlantic and North Pacific. It spends most of its time at sea, only coming to land to breed on rocky cliff shores or islands.

Guillemots are fast in direct flight but are not very agile. They can manoeuvre better underwater, where they typically dive to depths of 30–60m. They breed in colonies at high densities; nesting pairs may be in bodily contact with their neighbours. They make no nest; their single egg is incubated on a bare rock ledge on a cliff face.

Some individuals in the North Atlantic, known as "bridled guillemots", have a white ring around the eye extending back as a white line. This is not a distinct subspecies, but a polymorphism that becomes more common the farther north the birds breed."

Anthodites (Skyline Caverns, Front Royal, Virginia, USA) 3 by James St. John

1

Anthodites in a cave in Virginia, USA.

"Cave formations" in caves are technically called speleothem. Most speleothem is composed of travertine, a crystalline-textured chemical sedimentary rock composed of calcite (CaCO3). Travertine forms in most caves and at some springs by precipitation of crystals from water. Travertine speleothem occurs in a wide variety of forms. The most common variety of travertine speleothem is dripstone, which forms by the action of dripping water. The second-most common type of travertine speleothem is flowstone, which forms by precipitation of crystals from relatively thin films of flowing water. Flowstone typically has the appearance of a frozen waterfalls.

Shown above are anthodites, a scarce variety of speleothem that was first described from this very cave - Skyline Caverns in Virginia. Anthodites are radiating clusters of quill-like to slightly vermiform structures. Individual anthodite quills are hollow. Mineral analysis by White (1994) has shown that they are composed of aragonite (CaCO3), which is a polymorph of calcite. Some have recrystallized to calcite. The anthodites of Skyline Caverns were originally in sealed chambers in a mostly-sediment filled cave passage. During tourist trail construction, workers dug out sediments and encountered small chambers having common anthodites. They were subsequently named and described in the literature in 1949. The anthodite-bearing chambers were unusual in having near-vacuum conditions. Upon opening one chamber, a worker's hat was sucked in by the low air pressure.

When pure calcium carbonate, anthodites are white-colored. The yellows and browns seen above are from iron oxides.

Skyline Caverns is developed in structurally tilted carbonates (mixed dolostones and limestones) of the Rockdale Run Formation (Beekmantown Group, Lower Ordovician).

The mineral marcasite P1290083 by John Pitts

Marcasite, whose name is derived from the Arabic word for pyrite, is a common and an attractive mineral. The two minerals, marcasite and pyrite, are often confused due to their similar characteristics. Marcasite is a polymorph of pyrite which means that it has the same chemistry as pyrite but a different structure and, therefore, different symmetry and crystal shapes. The marcasite/pyrite polymorh pair is probably the most famous polymorph pair next to the diamond/graphite pair. Adding to the confusion between marcasite and pyrite is the use of the word marcasite as a jewelry trade name. The term is applied to small polished and faceted stones that are inlayed in sterling silver. But even though they are called marcasite, they are actually pyrite.

Marcasite is difficult to distinguish from pyrite when a lack of distinctive crystal habits exists. In fact, many specimens have been wrongly identified as pyrite or marcasite by even experienced mineral collectors. For many years the iron sulfide "Suns" found in Illinois coal mines were called "Marcasite Suns" (also known as "Marcasite Dollars") until X-ray studies showed them to be mostly pyrite. They have a habit that looks like marcasite. The possibility that they were originally marcasite and then later transformed into pyrite is being studied. Now they are correctly called "Pyrite Suns", but the confusion still exists. Many marcasite specimens are distinctive enough to reveal their true identity and make interesting and beautiful display specimens.

The most famous habit for marcasite is its "cock's comb" twinned habit. The crystals appear like a roster's head crest, hence the name. The habit is very distinctive and can not be mistaken for any other mineral.

Marcasite has been known to pseudomorph other minerals. A pseudomorph is an atom by atom replacement of one mineral's chemistry for another. If done subtly, the replacement can leave the old mineral's shape intact. The effect is one mineral in the shape of another, hence the term pseudomorph (Latin for false shape). Marcasite has pseudomorphed pyrite, gypsum, fluorite and others. At other times marcasite is pseudomorphed itself into the iron oxide mineral goethite. Often the replacement is only peripheral and leaves a thin skin of iron oxides on the crystals. These iron oxides are seen as an iridescence sheen and can provide marcasite specimens with quite an attractive and colorful appearance. These oxides may also have a positive effect in slowing marcasite's unfortunate deterioration.

Over a period of years, marcasite will oxidize in collections, freeing sulfur which forms sulfuric acid. The acid will then attack the paper label and even the cardboard box holding the specimen. Over a period of decades, most marcasite specimens will have disintegrated into an undesirable dust along with deteriorated paper scraps. A sulfur smell released during this reaction is often the easiest characteristic distinguishing Marcasite from Pyrite. The reaction is triggered by exposure to air and is an exothermic reaction, meaning that the reaction releases heat. This does not mean that marcasite hand specimens will feel warm to the touch, but in some marcasite rich portions of certain mines the mine walls would get too hot to touch because of this reaction. Ironically, specimens with iridescent oxide coatings have shown a resistance to deterioration and seem to survive longer than "fresh" maracasites. Either way marcasite is an interesting and attractive mineral and even with the slow deterioration can be a pleasure to own for many many years.

Marcasite can be formed as both a primary or a secondary mineral. It typically forms under low-temperature highly acidic conditions. It occurs in sedimentary rocks (shales, limestones and low grade coals) as well as in low temperature hydrothermal veins. Commonly associated minerals include pyrite, pyrrhotite, galena, sphalerite, fluorite, dolomite and calcite.[1]

As a primary mineral it forms nodules, concretions and crystals in a variety of sedimentary rock, such as at Dover, Kent, England, where it forms as sharp individual crystals and crystal groups, and nodules (similar to those shown here) in chalk.

As a secondary mineral it forms by chemical alteration of a primary mineral such as pyrrhotite or chalcopyrite.

Marcasite reacts more readily than pyrite under conditions of high humidity. The product of this disintegration is iron(II) sulfate and sulfuric acid. The hydrous iron sulfate forms a white powder consisting of the mineral melanterite, FeSO4·7H2O.[5]

This disintegration of marcasite in mineral collections is known as "pyrite decay". When a specimen goes through pyrite decay, the marcasite reacts with moisture and oxygen in the air, the sulfur oxidizing and combining with water to produce sulfuric acid that attacks other sulfide minerals and mineral labels. Low humidity (less than 60%) storage conditions prevents or slows the reaction.[6]

Aphyric rhyolitic obsidian (Roaring Mountain Member, Plateau Rhyolite, Upper Pleistocene, ~59 ka; Obsidian Cliff, Yellowstone, Wyoming, USA) 1 by James St. John

Obsidian in the Pleistocene of Wyoming, USA.

Obsidian is a glassy-textured, extrusive igneous rock. Glassy-textured rocks have no crystals at all. They form by very rapid cooling of lava or by cooling of high-viscosity lava. Most obsidians form by the latter. Obsidian can be felsic, intermediate, mafic, or alkaline in chemistry. Most are felsic to intermediate.

A famous locality in North America is Obsidian Cliff at Yellowstone, Wyoming. It is a Pleistocene-aged lava flow with the chemistry of rhyolite (= a light-colored, felsic, aphanitic, extrusive igneous rock). The cliff itself shows columnar jointing. The rocks principally range from aphyric rhyolitic obsidian to partially devitrified rhyolitic obsidian. Lithophysae are sometimes present. Extremely small, microscopic crystals are present - they can be seen in thin sections. Some samples are reported to have small olivine phenocrysts. Small clusters of crystals, composed of plagioclase feldspar, pyroxene, and olivine, are sometimes present.

Many of the whitish-colored spots and bands running through most Obsidian Cliff rock samples are areas of devitrification. Glass is unstable on geologic times scales and it slowly crystallizes. The light-colored spots and bands are now non-glassy. Spotted, partially devitrified obsidian is known by the rockhound term "snowflake obsidian" (see: www.flickr.com/photos/jsjgeology/16561606417). The spots are composed of silica (SiO2), but are not quartz. Rather, they are composed of a polymorph of quartz - cristobalite.

Chrysotile asbestos veins in serpentinized komatiite (Upper Komatiitic Unit, Kidd-Munro Assemblage, Neoarchean, 2.711-2.717 Ga; southwest of the Potter Mine, east of Timmins, Ontario, Canada) 3 by James St. John

Chrysotile asbestos veins in serpentinized komatiite in the Precambrian of Ontario, Canada.

Komatiites are very rare, magnesium-rich, extrusive, ultramafic igneous rocks. They are named after the Komati River Valley in South Africa, the type locality. Komatiite is an exceedingly rare type of lava. No volcano on Earth erupts this material today. Komatiites are essentially restricted to the Archean (4.55 to 2.5 billion years ago). Experimental evidence has shown that komatiite lavas, when originally erupted, were considerably hotter (~1600º C) than any modern lava type on Earth. This indicates that Earth’s mantle was much hotter than now. Other geologic evidence also indicates that early Earth’s heat flux was much higher than today’s.

Komatiite lava had a very low viscosity - it could flow like an ultradense gas. This property permitted the solidification of some individual lava flows that are only 1 cm thick.

The classic texture of komatiites is spinifex texture, named after clumps of long, spiky (& painful!) grasses. Komatiites with spinifex texture have short to long blades or plates of olivine mixed with smaller-scale blades of pyroxene.

All Archean komatiites are metamorphosed - the original igneous mineralogy (olivine, pyroxene, minor chromite, etc.) is gone to mostly gone. Such rocks are best termed metakomatiites, but the prefix “meta-” is usually not specified in writing.

Komatiites have economic significance, as many are closely associated with copper-nickel minerals (chalcopyrite & pentlandite), plus minor platinum-group elements, arsenides, bismuthides, and maybe a little gold and silver. Komatiites are a world-class source of nickel in Canada and Western Australia.

The outcrop seen here is part of a komatiite "lava lake" next to the Potter Mine in Ontario, Canada. This is near the world-famous Pyke Hill locality, which has numerous, thin komatiite lava flows. The rocks in the Potter Mine-Pyke Hill area are part of the Kidd-Munro Assemblage, which consists of ultramafic and mafic volcanic rocks intruded by mafic to ultramafic dikes and sill-like bodies. Minor felsic volcanic rocks are also present. Volcanogenic massive sulfide deposits occur in the Kidd-Munro Assemblage - they have been mined at the Texas Gulf Mine and the Potter Mine.

The rocks at this particular site were originally interpreted as part of a relatively thick komatiite lava lake, the last feature of a volcanic eruption. A newer interpretation says that this is a series of thick komatiite sheet flows (at least 6) in a paleo-depression. A thin lava lake may have originally capped the succession.

This is an exposure of serpentinized komatiite. The light-colored linear features running through the rock are "veins" of asbestos. There are several minerals colloquially known as "asbestos". The most common is "white asbestos", which is a mineral called chrysotile. It is one of three polymorphs of serpentine (= magnesium hydroxy-silicate, Mg3Si2O5(OH)4). Other varieties include “blue asbestos” (= crocidolite amphibole) and “brown asbestos” (= amosite amphibole). Chrysotile serpentine has a whitish to greenish color, a silky luster, and fibrous fracture.

Camponotus (Tanæmyrmex) æthiops (Latreille 1798) ☿ (Hymenoptera Formicoidea Formicidæ Formicinæ Camponotini) by Elena Regina

Illustration for a comparative ecophylogenetic analysis of local myrmecofaunas, based on r/K selection theory and intra / interspecific parabiosis / lestobiosis, particularly focused on allochthonous and invasive species.

[Camponotus Mayr 1861: 1,083+†29 (IT: 19+†0) spp (41.2-0.0 mya)]

Parabiotic of Crematogaster scutellaris, Lasius emarginatus, Lasius lasioides, Pheidole pallidula, Solenopsis fugax, Tapinoma magnum.

Camponotus is an extremely large and complex, globally distributed genus. At present, nearly 500 sspp belonging to 45 sgg have been described and it could well be the largest ant genus of all. The enormous species richness, high levels of intraspecific and geographic variation and polymorphism render the taxonomy of Camponotus one of the most complex and difficult. Revisionary studies are generally confined to species groups and/or small geographical regions. These ants live in a variety of habitats and microhabitats and the sheer size of the genus makes any characterisation of their biology challenging. Nests are built in the ground, in rotten branches or twigs, or rarely into living wood and most spp possess a highly generalistic diet.

A mineral is a naturally-occurring, solid, inorganic, crystalline substance having a fairly definite chemical composition and having fairly definite physical properties. At its simplest, a mineral is a naturally-occurring solid chemical. Currently, there are over 6100 named and described minerals - about 200 of them are common and about 20 of them are very common. Mineral classification is based on anion chemistry. Major categories of minerals are: elements, sulfides, oxides, halides, carbonates, sulfates, phosphates, and silicates.

The carbonate minerals all contain one or more carbonate (CO3-2) anions.

Aragonite has the same chemistry as calcite - it is calcium carbonate (CaCO3). However, aragonite has a different molecular structure - the atoms are packed differently. Different minerals having the same chemical formula are called "polymorphs" (another good example is graphite and diamond - both are carbon, C).

Unlike calcite, aragonite forms crystals in the orthorhombic class. Many aragonite crystals are acicular (needle-like) or pseudohexagonal. The latter is the result of six orthorhombic prisms growing parallel to each other. The sample seen here is a radiating cluster of pseudohexagonal, cyclic-twinned aragonite masses.

Aragonite is slightly harder than calcite, at H=3.5 to 4, occurs in many colors, and easily bubbles in acid. Aragonite is a little bit more dense than calcite, due to closer packing of atoms.

Most modern seashells and coral skeletons are composed of the aragonite. Whitish-colored lime sand beaches in the world are aragonitic. Occasionally, "whitings" are seen in shallow, warm ocean environments. Whitings (cloudy, milky seawater) turn out to have numerous tiny, hair-like needles of aragonite.

In the rock record, aragonitic or aragonite-rich sediments convert to calcite over time. Cenozoic-aged carbonate sedimentary rocks are often aragonitic. Mesozoic- and Paleozoic-aged carbonates are almost always calcitic. Many ancient fossils have had their aragonitic shells dissolved away. Ancient shells that were originally calcitic are often still well preserved.

Seen here are aragonitic cave pearls, a type of speleothem ("cave formation"). Cave pearls are spherical to subspherical to irregularly-shaped and concentrically-layered. They form as minerals precipitate around tiny loose grains in shallow cave pools that are continuously agitated by dripping water. Some cave pearls are loose, while others get cemented to the underlying substrate or to adjacent cave pearls.

Guillemots are fast in direct flight but are not very agile. They can manoeuvre better underwater, where they typically dive to depths of 30–60m. They breed in colonies at high densities; nesting pairs may be in bodily contact with their neighbours. They make no nest; their single egg is incubated on a bare rock ledge on a cliff face.

Some individuals in the North Atlantic, known as "bridled guillemots", have a white ring around the eye extending back as a white line. This is not a distinct subspecies, but a polymorphism that becomes more common the farther north the birds breed."

Partially devitrified rhyolitic obsidian (Roaring Mountain Member, Plateau Rhyolite, Upper Pleistocene, ~59 ka; Obsidian Cliff, Yellowstone, Wyoming, USA) 5 by James St. John

Obsidian in the Pleistocene of Wyoming, USA.

Obsidian is a glassy-textured, extrusive igneous rock. Glassy-textured rocks have no crystals at all. They form by very rapid cooling of lava or by cooling of high-viscosity lava. Most obsidians form by the latter. Obsidian can be felsic, intermediate, mafic, or alkaline in chemistry. Most are felsic to intermediate.

A famous locality in North America is Obsidian Cliff at Yellowstone, Wyoming. It is a Pleistocene-aged lava flow with the chemistry of rhyolite (= a light-colored, felsic, aphanitic, extrusive igneous rock). The cliff itself shows columnar jointing. The rocks principally range from aphyric rhyolitic obsidian to partially devitrified rhyolitic obsidian. Lithophysae are sometimes present. Extremely small, microscopic crystals are present - they can be seen in thin sections. Some samples are reported to have small olivine phenocrysts. Small clusters of crystals, composed of plagioclase feldspar, pyroxene, and olivine, are sometimes present.

Many of the whitish-colored spots and bands running through most Obsidian Cliff rock samples are areas of devitrification. Glass is unstable on geologic times scales and it slowly crystallizes. The light-colored spots and bands are now non-glassy. Spotted, partially devitrified obsidian is known by the rockhound term "snowflake obsidian" (see: www.flickr.com/photos/jsjgeology/16561606417). The spots are composed of silica (SiO2), but are not quartz. Rather, they are composed of a polymorph of quartz - cristobalite.

Snowflake obsidian 2 by James St. John

(~5.7 centimeters across at its widest)

---------------------------------------------------------

Igneous rocks form by the cooling & crystallization of hot, molten rock (magma & lava). If this happens at or near the land surface, or on the seafloor, they are extrusive igneous rocks. If this happens deep underground, they are intrusive igneous rocks. Most igneous rocks have a crystalline texture, but some are clastic, vesicular, frothy, or glassy.

Obsidian is readily identifiable. It is a glassy-textured, extrusive igneous rock. Obsidian is natural glass - it lacks crystals, and therefore lacks minerals. Obsidian is typically black in color, but most obsidians have a felsic to intermediate chemistry. Felsic igneous rocks are generally light-colored, so a felsic obsidian seems a paradox. Mafic obsidians are scarce, but they are also black and glassy.

Obsidian is an uncommon rock, but can be examined at several famous localities in America, such as Obsidian Cliff at the Yellowstone Hotspot (northwestern Wyoming, USA) and Big Obsidian Flow at the Newberry Volcano (central Oregon, USA).

Obsidian is moderately hard and has a conchoidal fracture (smooth and curved fracture surface), with sharp broken edges. Freshly-broken obsidian has the sharpest edges of any material known, natural or man-made (as seen under a scanning electron microscope).

Obsidian forms two ways: 1) very rapid cooling of lava, which prevents the formation of crystals; 2) cooling of high-viscosity lava, which prevents easy movement of atoms to form crystals. An example of obsidian that formed the first way is along the margins of basaltic lava flows at Kilaeua Volcano (Hawaii Hotspot, central Pacific Ocean). The obsidian sample seen here formed the second way.

Obsidian is unstable on geologic time scales - it will slowly convert to material that is not obsidian. A partially-converted obsidian is a distinctive rock called snowflake obsidian. The black portions of the rock seen here are rhyolitic obsidian (glass). The white patches ("snowflakes") are devitrification spots composed of cristobalite (SiO2, a polymorph of quartz).

Anthodites (Skyline Caverns, Front Royal, Virginia, USA) 22 by James St. John

1

Anthodites in a cave in Virginia, USA.

"Cave formations" in caves are technically called speleothem. Most speleothem is composed of travertine, a crystalline-textured chemical sedimentary rock composed of calcite (CaCO3). Travertine forms in most caves and at some springs by precipitation of crystals from water. Travertine speleothem occurs in a wide variety of forms. The most common variety of travertine speleothem is dripstone, which forms by the action of dripping water. The second-most common type of travertine speleothem is flowstone, which forms by precipitation of crystals from relatively thin films of flowing water. Flowstone typically has the appearance of a frozen waterfalls.

Shown above are anthodites, a scarce variety of speleothem that was first described from this very cave - Skyline Caverns in Virginia. Anthodites are radiating clusters of quill-like to slightly vermiform structures. Individual anthodite quills are hollow. Mineral analysis by White (1994) has shown that they are composed of aragonite (CaCO3), which is a polymorph of calcite. Some have recrystallized to calcite. The anthodites of Skyline Caverns were originally in sealed chambers in a mostly-sediment filled cave passage. During tourist trail construction, workers dug out sediments and encountered small chambers having common anthodites. They were subsequently named and described in the literature in 1949. The anthodite-bearing chambers were unusual in having near-vacuum conditions. Upon opening one chamber, a worker's hat was sucked in by the low air pressure.

When pure calcium carbonate, anthodites are white-colored. The yellows and browns seen above are from iron oxides. The green coloration is from algae that grows in tourist trail lighting.

Skyline Caverns is developed in structurally tilted carbonates (mixed dolostones and limestones) of the Rockdale Run Formation (Beekmantown Group, Lower Ordovician).

As borboletas são insectos da ordem Lepidoptera classificados nas super-famílias Hesperioidea e Papilionoidea, que constituem o grupo informal Rhopalocera.

As borboletas têm dois pares de asas membranosas cobertas de escamas e peças bucais adaptadas a sucção. Distinguem-se das traças (mariposas) pelas antenas rectilíneas que terminam numa bola, pelos hábitos de vida diurnos, pela metamorfose que decorre dentro de uma crisálida rígida e pelo abdómen fino e alongado. Quando em repouso, as borboletas dobram as suas asas para cima.

As borboletas são importantes polinizadores de diversas espécies de plantas.

O ciclo de vida das borboletas engloba as seguintes etapas:

1) ovo→ fase pré-larval

2) larva→ chamada também de lagarta ou taturana,

3) pupa→ que se desenvolve dentro da crisálida (ou casulo)

4) imago→ fase adulta

_______________________

A butterfly is any of several groups of mainly day-flying insects of the order Lepidoptera, the butterflies and moths. Like other holometabolous insects, butterflies' life cycle consists of four parts, egg, larva, pupa and adult. Most species are diurnal. Butterflies have large, often brightly coloured wings, and conspicuous, fluttering flight. Butterflies comprise the true butterflies (superfamily Papilionoidea), the skippers (superfamily Hesperioidea) and the moth-butterflies (superfamily Hedyloidea). All the many other families within the Lepidoptera are referred to as moths.

Butterflies exhibit polymorphism, mimicry and aposematism. Some, like the Monarch, will migrate over long distances. Some butterflies have evolved symbiotic and parasitic relationships with social insects such as ants. Butterflies are important economically as agents of pollination. The caterpillars of some butterflies eat harmful insects. A few species are pests because in their larval stages they can damage domestic crops or trees. Culturally, butterflies are a popular motif in the visual and literary arts.

Chiastolite andalusite 1 by James St. John

1

(cut & polished slice; 3.5 centimeters across at its widest)

---------------------------------

A mineral is a naturally-occurring, solid, inorganic, crystalline substance having a fairly definite chemical composition and having fairly definite physical properties. At its simplest, a mineral is a naturally-occurring solid chemical. Currently, there are over 5800 named and described minerals - about 200 of them are common and about 20 of them are very common. Mineral classification is based on anion chemistry. Major categories of minerals are: elements, sulfides, oxides, halides, carbonates, sulfates, phosphates, and silicates.

The silicates are the most abundant and chemically complex group of minerals. All silicates have silica as the basis for their chemistry. "Silica" refers to SiO2 chemistry. The fundamental molecular unit of silica is one small silicon atom surrounded by four large oxygen atoms in the shape of a triangular pyramid - this is the silica tetrahedron - SiO4. Each oxygen atom is shared by two silicon atoms, so only half of the four oxygens "belong" to each silicon. The resulting formula for silica is thus SiO2, not SiO4.

The simplest & most abundant silicate mineral in the Earth's crust is quartz (SiO2). All other silicates have silica + impurities. Many silicates have a significant percentage of aluminum (the aluminosilicates).

Andalusite is an aluminum silicate mineral, Al2SiO5. This chemical occurs as three different polymorphs - andalusite, kyanite, and sillimanite. Andalusite is a metamorphic mineral. It has a nonmetallic luster and varies in color, but always has a white streak. It is hard (H = ~7) and has cleavage.

Chiastolite is a variety of andaulsite having dark-colored inclusions that result in a flower-like, tetraradiate structure.

The spots are composed of silica (SiO2), but are not quartz. Rather, they are composed of a polymorph of quartz - cristobalite.

The subrounded cavities are lithophysae - they formed before the rock completely solidified. The original lava flow had some subspherical structures known as spherulites, composed of glassy to cryptocrystalline material (many felsic extrusive igneous rocks have these). Expanding gases in the spherulites destroyed this material, resulting in partially empty spaces.

Wikipedia (edited): "The common murre or common guillemot (Uria aalge) is a large auk. It has a circumpolar distribution, occurring in low-Arctic and boreal waters in the North Atlantic and North Pacific. It spends most of its time at sea, only coming to land to breed on rocky cliff shores or islands.

Guillemots are fast in direct flight but are not very agile. They can manoeuvre better underwater, where they typically dive to depths of 30–60m. They breed in colonies at high densities; nesting pairs may be in bodily contact with their neighbours. They make no nest; their single egg is incubated on a bare rock ledge on a cliff face.

Some individuals in the North Atlantic, known as "bridled guillemots", have a white ring around the eye extending back as a white line. This is not a distinct subspecies, but a polymorphism that becomes more common the farther north the birds breed."
