Most habitats - Gardens, Woodlands, Hedgerows.
Widespread in Ireland.
Nettles.
50-55mm (2.44 inches)
This is a very common butterfly which regularly frequents gardens, particularly favouring Buddlea bushes.
It is mainly reddish-orange with black markings and blue spots around the border. In contrast, the underside is quite dull.
It can be found sometimes hibernating in houses.
Habitat: The Small Tortoiseshell is widespread throughout Ireland.
There are two broods annually.
Larval Food Plant: Common Nettle Urtica dioica
Flight Time:
March to April or later (after hibernation)
July to early August
Mid-August to mid-September
Hibernation: Overwinters as an adult butterfly.
Small Tortoiseshell butterflies seen between November
and February have probably been disturbed from their
hibernation sites.
This butterfly, because of its affinity for nectar from the Butterfly Bush Buddleia and Michelmas Daisy Aster and
its hibernation habits, is one of Ireland's best recognised species.
Ovum:
The greenish globular eggs are laid in clusters of about 80 on the underside of a growing leaf of the Common
Nettle Urtica dioica. They can be found from March onwards but more commonly in April/May and July/August.
Larva:
The larvae hatch in 7-21 days. The mature larvae vary in colour from yellow to black, most frequently yellow,
closely covered in black speckling and short hairs. There is a black mediodorsal line bordered by clear
ground colour, and two broken bands of yellow along each side. Spiracles are black and ringed with yellow.
The early instars remain together and spin a tent by drawing together a few leaves at the top of the plant
with silk into which they retreat to live, moult and feed. They move on to form a new retreat on fresh nettle
leaves as each leafy tent is consumed.
By the final instar in May/June (1st brood), and July/August (2nd brood) they become more solitary.
The larval stage takes approximately 4 weeks after which the larvae enter the pupal stage.
Pupa:
The pupa hangs vertically downwards from vegetation or walls or under ledges about a metre above ground,
suspended from a silken pad by its cremasteral hooks.
Adult:
The adult emerges in 2-4 weeks. The second brood of Butterflies, that emerges from pupation from mid-August
onwards, enter hibernation between mid-September and November. They overwinter in sheds, attics
and in houses and resume activity the following Spring. Mating takes place after overwintering and eggs are
laid from March onwards.

Damselflies are insects of the suborder Zygoptera in the order Odonata. They are similar to dragonflies, which constitute the other odonatan suborder, Anisoptera, but are smaller, have slimmer bodies, and most species fold the wings along the body when at rest. An ancient group, damselflies have existed since at least the Lower Permian, and are found on every continent except Antarctica.
All damselflies are predatory; both nymphs and adults eat other insects. The nymphs are aquatic, with different species living in a variety of freshwater habitats including acid bogs, ponds, lakes and rivers. The nymphs moult repeatedly, at the last moult climbing out of the water to undergo metamorphosis. The skin splits down the back, they emerge and inflate their wings and abdomen to gain their adult form. Their presence on a body of water indicates that it is relatively unpolluted, but their dependence on freshwater makes them vulnerable to damage to their wetland habitats.
Some species of damselfly have elaborate courtship behaviours. Many species are sexually dimorphic, the males often being more brightly coloured than the females. Like dragonflies, they reproduce using indirect insemination and delayed fertilisation. A mating pair form a shape known as a "heart" or "wheel", the male clasping the female at the back of the head, the female curling her abdomen down to pick up sperm from secondary genitalia at the base of the male's abdomen. The pair often remain together with the male still clasping the female while she lays eggs within the tissue of plants in or near water using a robust ovipositor.
Fishing flies that mimic damselfly nymphs are used in wet-fly fishing. Damselflies sometimes provide the subject for personal jewellery such as brooches.

Con il termine comune di insetto stecco si identifica il Bacillus rossius, un animale appartenente all’ordine dei Fasmoidei.
Il suo nome deriva dalla singolare conformazione del suo corpo: appare infatti simile ai rametti più esili delle piante, sia per quanto riguarda il colore – marrone o verde – che per strisce e piccole protuberanze simili alle rigature del legno.
Il corpo dell’insetto stecco si caratterizza per una lunghezza ragguardevole – circa 12 centimetri per le femmine e 6.5 per i maschi – nonché per la sua struttura esile e allungata.
Ogni esemplare prevede poi quattro zampe posteriori altrettanto lunghe e sottili, a cui si aggiunge un paio frontale decisamente più allungato.

Family: Papilionidae
Genus: Papilio
Species: P. machaon
Binomial name
Papilio machaon
Linnaeus, 1758
Introduction
Back in the 18th century when Linnaeus created the System Naturae, the word Papilio was used as the genus name for every known species of butterfly in the world. Since then much has been learnt about the relationships between different species. Consequently most have been reassigned to new genera, and only about 215 of the 17600 currently known species are retained in Papilio.
Papilio machaon is widespread and common throughout much of the northern hemisphere. It occurs over the whole of continental Europe, eastward across temperate Asia to Japan; in Africa north of the Sahara; and throughout much of North America. In Britain it is locally common on the Norfolk Broads, an area of fenland and lakes in eastern England.
Individuals originating from France occasionally migrate across the English Channel and have been periodically recorded in Hampshire, Dorset, Sussex and the Isle of Wight, but such sightings are very rare - perhaps one or two sightings per year. Genuine migrants can usually be recognised by their faded and worn appearance. Fresh looking insects seen anywhere apart from Norfolk can be attributed to escaped or deliberately released livestock - both the British subspecies brittanicus and the continental gorganus are commonly reared by hobbyists. ( it is illegal to capture or breed stock of British origin, but nevertheless a widespread practice ).
There are no similar species occurring in Britain. On the Mediterranean islands of Corsica and Sardinia machaon shares it's habitat with Papilio hospiton, which is similarly marked but has much shorter tails on the hindwings. In Algeria the distribution of machaon overlaps that of the Saharan Swallowtail Papilio saharae, which is identical in appearance except for the antennae, which have 30 segments in saharae, and 33-36 segments in machaon.
Habitats
Throughout most of it's range the Swallowtail shows itself to be highly adaptable, utilising a wide variety of habitats including sub-arctic tundra in Canada, prairies, woodlands and arid canyons in the south of the USA; hay meadows, roadside verges, river banks and sub-alpine pastures in Europe; high montane habitats in the Atlas mountains of north Africa, and semi-cultivated habitats in the Mediterranean area.
It's adaptability extends also to it's choice of foodplants - in North America the caterpillars usually feed on Compositae ( Artimesia, Petasites ), while in Europe Rutaceae ( Ruta, Haplophyllum ) and Umbelliferae ( Foeniculum, Peucidanum etc ) are used instead. In Britain however the butterfly is restricted to a single foodplant - milk parsley, and breeds only at a very small number of wet fenland habitats in north-east Norfolk. Individual specimens have been tagged and found to fly over quite a large area, often reaching adjacent fens, but the butterflies do not stray beyond the general area of the broads.
Several centuries ago the species almost certainly occurred as a resident species over a much wider area of southern and eastern England, but later contracted it's range to the Great Fen - a vast area of wetlands covering Cambridgeshire, Lincolnshire and Norfolk. Following the drainage of this area, and it's conversion to agriculture, the butterfly was forced to contract it's range even further - to the Norfolk Broads. In such isolation the genetic diversity would have diminished, causing the so-called "sub-species" machaon brittanicus to become far less adaptable, and to acquire minor differences in appearance from the ancestral stock.
In the last 100 years the average wingspan of Swallowtails, and the average width of the thorax, have reduced in size, an indicator of further genetic impoverishment, which is likely to result in further contraction and eventual extinction. Expansion of the gene pool can only be accomplished by the introduction of genetically richer livestock from Europe, a policy which hopefully will eventually be adopted by conservation groups.
Although the butterfly only breeds in the wet fenlands and broads of Norfolk, migrants from France are periodically observed at coastal sites in Dorset, Hampshire, the Isle of Wight, Sussex and Kent. On 1st Sept 2003 for example I watched an immigrant Swallowtail flying across a main road at Milford-on-Sea in Hampshire. In most years less than half a dozen are recorded, usually in August or September. Individuals very occasionally penetrate further inland, and are reputed to sometimes breed on chalk grasslands, reportedly feeding as larvae on wild carrot Daucus carota, although I know of no recent records.
It is planned that by the end of the 21st century the Great Fens which formerly occupied much of eastern England will be partially restored, leading to a sizeable increase in suitable habitat. Whether such a project is feasible in the face of population expansion however remains to be seen.
Lifecycle
The butterfly is bivoltine on the continent, emerging in May and August, but in Britain the second brood is either partial or non-existent.
In the Norfolk fens where the butterflies emerge in late May, they lay their large brown globular eggs singly on the fine leaves of milk parsley Peucidanum palustre. The eggs are nearly always laid on the upper foliage of tall plants which project above the surrounding reedbeds. They hatch after about a week.
The young caterpillar is black, marked with a band of white. It looks remarkably like a small bird-dropping as it rests openly on the leaves. According to Thomas the camouflage is not effective against spiders, which may predate up to 65% of 1st instar larvae. When fully grown in July, the caterpillar is a most magnificent creature - bright green, marked with narrow black bands and orange spots. Behind it's head is an eversible fleshy pink forked structure called an osmaterium, which is raised if the larva is irritated. This structure emits pungent chemicals, capable of deterring ants, wasps, and flies, but does not deter birds - reed buntings, sedge warblers and bearded tits between them devouring at least 50% of mature larvae.
The chrysalis occurs in 2 colour forms, being either plain green, or light brown with a dark lateral stripe. It is attached vertically by a thin silken girdle and by the cremaster, usually low down on the stem of a reed, where it hibernates until the following May.
Adult behaviour
The butterfly has a characteristic powerful gliding flight, and is capable of covering large distances. In France and Spain for example I have often observed males indulging in "hill-topping", i.e. flying to congregate at the top of hills, where they compete for the attention of passing females. In Britain the butterfly breeds only on the flat terrain of Norfolk, and probably only covers short distances, although it can be seen crossing open expanses of water on the Broads.
On warm sunny days, male Swallowtails patrol back and forth along a regular route in search of females. Often both sexes home in on a particular clump of bushes where courtship and copulation take place. The pair often remain joined for 2 or 3 hours before the female departs to oviposit.
In the morning, and again in late afternoon both sexes can be seen flying freely about their habitat, pausing regularly to nectar at the pink flowers of angelica, knapweeds, marsh thistles, red campion, ragged robin and valerian. When nectaring they keep their wings constantly fluttering to prevent the weight of their bodies from dragging down on the fragile flowers. This fluttering behaviour is typical of all Papilioninae, wherever they occur in the world. In Norfolk the butterflies also often nectar at the spectacular bright yellow flowers of yellow iris.
In cool but sunny weather, or during periods of hazy sunshine, Swallowtails can sometimes be seen basking amongst dry grasses. During overcast weather they roost hanging from reed stems, and probably also amongst the foliage of sallow and alder bushes, and other fenland vegetation.
In the French Alps and the Pyrenees the butterflies commonly indulge in mud-puddling - siphoning mineral-rich moisture from damp mud and cattle dung, but I have not observed this behaviour in Britain.

Colias croceus
(Geoffroy, 1785)
Open wings: Both sexes are bright mustard yellow. The apex and the wings margins are black in the case of females. The hindwings have black margins that stretch to the anal angle. There is a big black spot on each of the frontwings. There are females, known for its spiral shape, which are white instead of yellow, and seem grey because of a lot of dark scales on their hindwings.
Closed wings: They are white or greenish with white dark-rimmed spots in the shape of an eight. Spiral-shaped females are similar to female Berger's Clouded Yellow butterflies.
Similar species
Berger's Clouded Yellow: When their wings are open, male butterflies are less bright than the above species, and females are white. The black margins on hindwings are thinner and shorter, as they do not reach the anal angle, and without dark scales on the inner part of the female wings. This is why they are lighter than spiral-shaped Dark Clouded Yellow. The yellow colour is duller when they close wings. Spiral-shaped female butterflies are very similar and difficult to distinguish.
Biology and Habitat
There are several generations of the species throughout the year. Populations grow in winter and spring when butterflies come from Africa, as well as in autumn thanks to the butterflies that proceed from Central and Northern Europe.
Due to their migratory character and the fact that their caterpillars feed on leguminous wild plants, they can be seen in diverse habitats, spreading from high altitudes to urban zones, such as parks and gardens. It can also be seen along the coast and close to the sea while it migrates to the north.

Les larves de les cicadelles produisent avec la sève des plantes sur lesquelles elles se développent cette écume qui les camoufle.
Little Fly Thy summers play,
My thoughtless hand Has brush'd away.
Am not I A fly like thee?
Or art not thou A man like me?
For I dance And drink and sing
Till some blind hand Shall brush my wing.
If thought is life And strength and breath;
And the want of thought is death;
Then am I A happy fly,
If I live, Or if I die.
