Common Hoverfly (Melangyna viridiceps)
Feasting on the pollen of a Wandering Jew Flower.
You can see the pollen on it tongue.
“Sip bridle satiation,
oh, wistless awl,
so quick to puncture,
so pressed to roll
and pawl the advance.
Every lingering a scrape,
a further sharpened cog
that will sink into,
then stutter out,
segmentation,
stall after stall.”

Giant anteaters prey almost exclusively on social insects (i.e. ants and termites). Such dietary focus significantly shapes the physical form and behavior of the species. Giant anteaters do not have teeth; instead, they have tongues can reach as much as 610 mm (2 ft.) in length! As long as the tongue is, it is relatively narrow over the entirety of its length, with its widest point being only 10 to 15 mm (0.4 to 0.6 in.). They use this giant tongue to gather insects for food, extending it up to 150 times per minute.
Their tongues are covered with tiny spines which point toward the back of the throat. Additionally, their tongue is coated with a thick, sticky coat of saliva (which is secreted from relatively enlarged salivary glands). Prior to swallowing, the insect-coated tongue is firmly pressed against the anteater's hard upper palate – crushing their meal and easing ingestion.
The stomachs of anteaters do not secrete hydrochloric acid. Instead, they depend on the formic acid content of their ant-dominated diet to aid in digestion.
They can eat up to 30,000 insects a day.
Despite their coarse fur and thickened skin (particularly about the muzzle), giant anteaters may still be agitated by the large-jawed soldier castes of the ant and termite species upon which they feed. Accordingly, they avoid soldiers both actively and tactically. The anteater's typical feeding profile could be described as a lightening strike - quick feeding action over a short period. Such a clipped feeding incursion generally outpaces a given insect colony's ability to rapidly mount a defense; thus tactically avoiding the aggravation of soldier castes.
Giant anteaters tend to pursue the larger bodied social insects, while tamanduas and silky anteaters tend to prey on smaller insect fare. Such dietary segmentation allows for different anteater species to co-exist in the same region without being in direct predatory competition.
Giant anteaters are terrestrial. Unlike other anteater species, adult giant anteaters only rarely climb trees. Instead, its powerful forearms and prominent claws are used primarily for digging and ripping in the search for food.
While the giant anteater has five digits on each foot, their first digit is reduced and the second and third digits exhibit the long claws.
Anteaters are able to detect insects with their powerful sense of smell, 40 times that of man. If threatened, the typically non-vocal giant anteater may make a bellowing noise. Additionally, they will often rear up on their hind quarters and swipe with their (up to) 10 cm (4 in.) long foreclaws.
Anteaters do not walk on the soles of their forefeet. Rather, they flex the digits upward and turn the forefeet inward, such that the large foreclaws do not come in contact with the ground. Anteaters sleep as much as 15 hours each day.
As an outcome of their diet and lifestyle, anteaters have relatively low metabolic rates. As a stark example, the giant anteater has the lowest recorded body temperature of any placental mammal – 32.7° C (90.9°F).
When observed in regions without a significant human presence, giant eaters are diurnally active. However, giant anteaters appear to adopt a nocturnal lifestyle when living in more disturbed areas subject to human activity.
Giant anteaters, save for mother/young pairs, are generally solitary. Usually only one baby is born at a time. It nurses for 6 months and is carried on the mother's back for up to a year.
Leeches are segmented parasitic or predatory worms that belong to the phylum Annelida and comprise the subclass Hirudinea. They are closely related to the oligochaetes, which include the earthworm, and like them have soft, muscular, segmented bodies that can lengthen and contract. Both groups are hermaphrodites and have a clitellum, but leeches typically differ from the oligochaetes in having suckers at both ends and in having ring markings that do not correspond with their internal segmentation. The body is muscular and relatively solid, and the coelom, the spacious body cavity found in other annelids, is reduced to small channels. The majority of leeches live in freshwater habitats, while some species can be found in terrestrial or marine environments. The best-known species, such as the medicinal leech, Hirudo medicinalis, are hematophagous, attaching themselves to a host with a sucker and feeding on blood, having first secreted the peptide hirudin to prevent the blood from clotting. The jaws used to pierce the skin are replaced in other species by a proboscis which is pushed into the skin. A minority of leech species are predatory, mostly preying on small invertebrates. The eggs are enclosed in a cocoon, which in aquatic species is usually attached to an underwater surface; members of one family, Glossiphoniidae, exhibit parental care, the eggs being brooded by the parent. In terrestrial species, the cocoon is often concealed under a log, in a crevice or buried in damp soil. Almost seven hundred species of leech are currently recognised, of which some hundred are marine, ninety terrestrial and the remainder freshwater. Leeches have been used in medicine from ancient times until the 19th century to draw blood from patients. In modern times, leeches find medical use in treatment of joint diseases such as epicondylitis and osteoarthritis, extremity vein diseases, and in microsurgery, while hirudin is used as an anticoagulant drug to treat blood-clotting disorders.

These shots were both taken last year, i havent seen any of them this year yet but i do hope they return. I love how the yellow really shows off the segmentation of their bodies.

If you zoom in on the head of this eusocial wasp, you'll find that it has a drop of water on top of it.
As for species, it looks a bit odd with the more brown than black segmentation on the abdomen, but given the markings on the face and everything, I still think this is a common wasp (Vespula vulgaris) and not one of the other eleven eusocial species in Sweden.
I found it stationary on a leaf on a windy day close to the beach near my mom's summer house in Värmdö, Sweden.

On the morning lap with my dog I saw a stork on the wetland meadow in the vicinity of the camp I stayed. - Of course without camera. -
Quickly I went back and took the camera.
And fortunately the stork was still there.
I could take some photos, even in flight.
But I prefer to present this due to the image segmentation.
The next two mornings the stork did not come back.
During my stay I unfortunately didn't find the stork's nest.

Believe it or not, millipedes can make excellent pets; they don't bite, they can't sting, and those kept in captivity can live up to 10 years

American Giant Millipede – 2020SEP27 – Charlotte, NC
Look what I found! A Giant Millipede, Narceus americanus: it grows twice as large as any other North American millipede, a cylindrical millipede (distinguished from flat millipedes), dark reddish-brown or black, a red line on each segmente edge; like all millipedes, they have 2 pairs of legs on most segments, rather than 1 pair of legs on each segment (like a centipede).
Does it bite? No (uniike a centipede). What about cyanide? Although not this species, some secrete hydrogen cyanide, quite poisonous. Remember, millipedes are toxic – but as long as they are not eaten, hands washed after touching them, they're pretty harmless; however, many have a defensive secretion, benzoquinone, that can cause chemical burns on human skin, generally mild, but powerful enough to cause temporary skin discoloration, itching, and blisters – some millipedes’ secretions are much more powerful, though.
The division of an animal into repeating body parts is called segmentation, clearly seen in millipedes, the word meaning “one thousand foot;” despite that name, millipedes with the most legs come up shy of the 1,000-leg mark, only about 750.
Hope you enjoy the 10% of 99 captures I took here this day!

Millipedes – the term from two Latin words, mil, meaning thousand, and ped, meaning feet – have 2 pairs of legs per body segment; by contrast, centipedes have one pair of legs per segment

But what we would like to consider now is the actual appearance of man, his physical quality of 'image of God: which distinguishes him a priori from all other creatures on earth, so that to speak of the human body is almost to speak of man as such; our bodily form would in fact be unintelligible if it were not for our faculties of intelligence and liberty; it is on the contrary explicable only in terms of these qualities.
Let us say at once that the profanation of human beauty by the passions in no way authorises contempt for this work of the Creator: despite the good intentions of those who seek to defend virtue at the expense of truth and intelligence, to disparage this beauty is a kind of blasphemy and all the more so since the Avatara of necessity synthesises the total Creation in his body and so in its beauty.
Some will doubtless insist that all earthly beauty is imperfect and carries blemishes, but this is false in so far as they go on to deduce from this that there is no true beauty on earth. On the other hand, if earthly beauty can be perfect in its kind, it is none the less exclusive of other kinds, and so in a certain sense limited: the beauty of a rose cannot realise that of a water-lily, and in the same way human beauties, whether individual or racial, exclude one another; God alone possesses simultaneously all possible beauty, the Essence being beyond the segmentation of form.

The Perfect Storm - America Dark Enlightenment by Daniel Arrhakis (2025)
Neoreaction or “Dark Enlightenment” is the "new"formal and nostalgic elitist ideology.
In this absolutist restorationist conception, Trumpism is a intellectual counterculture for the limitation or destruction of the State, for an unregulated liberalism based on the power of the strongest, deep down in an Absolutist Fascist nature.
With great segmentation of the economy and social demographics in favor of an unregulated liberalism deep down in an Oligarchy of an Absolutist nature with unlimited and unquestionable power; to which all peoples and leaders of the world owe vassalage.
To achieve this goal, the deregulation of the world economy and the subversion of world decision-making centers is necessary, the destruction of the state as guarantor of rights and supports of minorities or the poorest as well.
Discredit and disinformation are essential to mold mindsets to new concepts of society and economy but also to question democratic institutions, the very division between political and judicial powers.
In this Trumpist conception Chaos is Democracy itself and Unquestionable Absolute Power the only possible Order in a society in which the law of the strongest prevails !
The Perfect Storm is there … and deep down everyone knew it would come … and many did nothing to avoid it !

A Tempestade Perfeita - America Dark Enlightenment de Daniel Arrhakis (2025)
Neoreação ou “Iluminismo Das Sombras” é a “nova” ideologia elitista formal e nostálgica.
Nesta conceção restauracionista absolutista, o trumpismo é uma contracultura intelectual para a limitação ou destruição do Estado, para um liberalismo desregulado baseado no poder do mais forte, profundamente enraizado numa natureza fascista absolutista.
Com grande segmentação da economia e da demografia social em prol de um liberalismo desregulado, no fundo de uma Oligarquia de cariz Absolutista com poder ilimitado e inquestionável; ao qual todos os povos e dirigentes do mundo devem vassalagem.
Para atingir este objetivo, é necessária a desregulação da economia mundial e a subversão dos centros de decisão mundiais, a destruição do Estado como garante dos direitos e apoio às minorias ou também aos mais pobres.
O Descrédito e a desinformação são essenciais para moldar mentalidades para novos conceitos de sociedade e de economia, mas também para questionar as instituições democráticas, a própria divisão entre os poderes político e judicial.
Nesta concepção trumpista o Caos é a própria Democracia e o Poder Absoluto Inquestionável é a única Ordem possível numa sociedade em que prevalece a lei do mais forte!
A tempestade perfeita está aí… e no fundo todos sabiam que ela viria… e muitos não fizeram nada para a evitar!
A few more iterations of my "Think Tank" (tachikoma) design using Hero Factory parts. I know they stretch the definition of a "Think Tank", as the body segmentation is more implied than well defined, nor are the sensor eyes pronounced in some (except for the "Scanner", of course), but think all they might still fit into the GiTS anime universe...
Abstract
To understand the evolutionary significance of geographic variation, one must identify the factors that generate phenotypic differences among populations. I examined the causes of geographic variation in and evolutionary history of number of trunk vertebrae in slender salamanders. Batrachoseps (Caudata: Plethodontidae). Number of trunk vertebrae varies at many taxonomic levels within Batrachoseps. Parallel clines in number occur along an environmental gradient in three lineages in the Coast Ranges of California. These parallel clines may signal either adaptation or a shared phenotypically plastic response to the environmental gradient. By raising eggs from 10 populations representing four species of Batrachoseps, I demonstrated that number of trunk vertebrae can be altered by the developmental temperature; however, the degree of plasticity is insufficient to account for geographic variation. Thus, the geographic variation results largely from genetic variation. Number of trunk vertebrae covaries with body size and shape in diverse vertebrate taxa, including Batrachoseps. I hypothesize that selection for different degrees of elongation, possibly related to fossoriality, has led to the extensive evolution of number of trunk vertebrae in Batrachoseps. Analysis of intrapopulational variation revealed sexual dimorphism in both body shape and number of trunk vertebrae, but no correlation between these variables in either sex. Females are more elongate than males, a pattern that has been attributed to fecundity selection in other taxa. Patterns of covariation among different classes of vertebrae suggest that some intrapopulational variation in number results from changes in vertebral identity rather than changes in segmentation.
