|The eggs are fusiform (tapered at both ends) and initially white in colour, later bright orange, then red. After 4-12 days the caterpillars hatch. They are elongated and reach body lengths of 30-35 mm. Young larvae up to the 2nd moulting are reddish-yellow which changes to yellowish brown, in the 3rd to 4th larval stage. above whitish-green and laterally known with fine-grained ...|
...-yellow which changes to yellowish brown, in the 3rd to 4th larval stage. above whitish-green and laterally known with fine-grained black dotting (warts). At the end of the last larval stage they are cyan in colour with a dark-green underside. The caterpillar has little green feet. Due to its appearance the caterpillar of the orange tip can be confused with that of the common brimstone butterfly (Gonepteryx rhamni), but can however be distinguished by its black warts. The caterpillar lives from June to August on its food plants, where it eats the flowers and the developing seed capsules. The most caterpillars can be found on tower mustard plants (Turritis glabra). When 2 caterpillars meet on a plant cannibalism can occur between the competitors due to limited food resources. They also eat Eggs from the same batch.
|The larvae hatch in September. They are nocturnal, but can also be found during the day on grasses. Their bodies are up to 75 mm in length and their colouration is very striking, almost unmistakeable. The basic body colour of the caterpillar is dark grey, and later changes to blue.
The entire body of the caterpillar is covered in a thick coat of long reddish-brown hair. These hairs break off when touched and can get stuck in the skin. A band of yellow to orange-yellow spots runs along each side of the caterpillar and next to this are short, thick, black tufts of hair. There are white tufts of hair in pairs and triplets, the whole way along the lower half of the sides.
On the upper surface of three segments of the back are broad tufts of long, orange hair...|
|The caterpillars are nocturnal and live on, and eat, the grasses Brachypodium sylvaticum, Agrostis capillaris, broch sedge (Carex divulsa) and Luzula forsteri. The caterpillar is long and thin. It can reach body lengths of 25 - 27 mm and is yellowish-green in colour. There is a dark green stripe, on the upper surface of the back and slightly dark green and bright green shimmering lines on the sides. The entire body of the...|
...is long and thin. It can reach body lengths of 25 - 27 mm and is yellowish-green in colour. There is a dark green stripe, on the upper surface of the back and slightly dark green and bright green shimmering lines on the sides. The entire body of the caterpillar is covered in individual, upright, light coloured hairs. The head is oval or round and clearly a blue-green colour. At the hind end a whitish tail boom is to see in the early larval stage. The caterpillars have stubby feet and are characterized by their excellent camouflage in the grasses where they live.
|.... It is common in Europe, Asia, North America and Australia.
The small white reaches wingspans of 40 - 50 mm. Its wings are white with black spots. The front wings have grey to black tips. The undersides of the hind wings are grey to yellow. The caterpillar is a dull green colour with light stripes on the sides. |
|The caterpillar is green. It has a dark stripe on its upper surface. The last segment bears the forked tail. The meadow brown is found almost everywhere, but is rare above 1600 metres.
Eggs are laid on the soil or on grass. The caterpillars shed their skin twice. They overwinter and pupate in May. The cocoon is spun on a blade of grass and is yellowish-green. The next adult meadow browns emerge in June.
The meadow brown is active from June to September. It reproduces once a year. ...|
|The caterpillar is bluish-green with white stripes. This species produces 2 new generations a year. The eggs are laid on wild grasses, in May or June, and again, in August. The caterpillars hatch from their eggs after about 10 days and feed on the wild grasses. They are nocturnal. The caterpillars of the first generation develop into adults in about a month, while the second generation overwinter. After the caterpillars have pupated, itís about two weeks until the new butterflies hatch. |
|The caterpillar is green and spiky. The white admiral is found in moist forests, wetlands, river valleys and in the mountains at altitudes of up to 1500 metres. |
|Some examples of natural enemies of orange tip caterpillar are tachina flies (Tachinidae) and braconids (Braconidae), which lay their eggs inside the caterpillars. After hatching, the larvae eat their host from inside out. At the end of July or in early August the caterpillars pupate with their heads upwards. Pupation occurs on the ground near the food plants or on the stalks or branches of other plants. The pupae are initially yellowish-green, later yellowish-brown or grey brown, and are shaped like a boat with a cre...|
|The caterpillar of the two-tailed pasha reaches a body length of 60 mm. It is green, with a bright yellow stripe on each side and is covered in small yellow dots. It is shaped like a slug, even in the embryonic state. The head has 4 reddish or brownish horns. The t...|
...d like a slug, even in the embryonic state. The head has 4 reddish or brownish horns. The two central ones protrude significantly in height above the others. The strikingly broad posterior end into direction of the head looks like being pressed. The caterpillars mainly feed on the leaves of the western strawberry tree (Arbutus unedo). They are very sensitive to frost. Therefore, this species is absent in a small area north of the Adriatic.
