| | 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 cres... | | |
| | | Fertilized females drop their eggs from the air onto grasslands. The caterpillars have a body length of about 25 mm and are greyish-brown to red in colour with fine, dark spots.They have a dark longitudinal line on their backs. The caterpillars live on Poaceae or Cyperaceae, which grow in the shadow of blackberry bushes. They pupate and overwinter between grasses, which they spin together. | | |
| Painted lady caterpillars feed on a variety of different plant families, above all,mallow (Malvaceae), Compositae (Asteraceae), Cucurbits (Cucurbitaceae), legume (Fabaceae), wine grape (Vitaceae), borage (Boraginaceae) and cabbage (Brassicaceae). They particularly like t...
...Vitaceae), borage (Boraginaceae) and cabbage (Brassicaceae). They particularly like the ordinary thistle (Cirsium vulgare), cabbage thistle (Cirsium oleraceum), Carduus thistles (Carduus sp.) and other plants from the thistle family. Painted lady caterpillars are also found on musk mallow (Malva moschata) and nettle (Urtica dioica). | | |
| | The caterpillars of the first new generation appear in June/July, those of the second generation appear in August/September. After 7-11 days the caterpillars are fully developed and pupate. The pupa is about 25 mm long, grey-brown to greenish-grey in colour and hangs upside down. The pupa remains in this position for approximately another 7-11 days until the new adult painted lady butterfly hatches. | | |
| | Lepidopterans usually only ingest liquid food (nectar, water). A few species live off animal excrement, urine, sweat, blood or even tears. Caterpillars often eat their own egg shells after hatching, and then feed on leaves, pine needles, flowers, seeds or fruits. Some caterpillars live as social parasites with ants. | | |
| | For humans, the larvae of the Bombycidae and the caterpillars of the silkmoth (silkworms) are of importance. These caterpillars are considered pests especially in gardens and monoculture farming, because an infestation leads to significant crop losses. Lepidopterans which suck blood or tears are considered to be disease vectors. | | |
| | Excentricus planicornis are often found on ruderal plants, especially herbs, deciduous trees or shrubs. Adults can be encountered from June to October. They prey on aphids, psyllids, tortrix moth caterpillars, ermine caterpillars and other arthropods. Occasionally, they also eat plant parts (berries, buds etc.). | | |
| | ...underside of the leaves of the caterpillar’s forage plants, for example on willow, hazel, fluttery elm, field elm, mountain elm, hops, great nettle, gooseberry and raspberry plants. Around 250 eggs are laid separately. 2 - 3 weeks later the solitary caterpillars hatch. During the day they stay on the underside of the leaves. The larval stage lasts 6 weeks and then the caterpillars pupate. The pupae are striking; the middle is constrictedly built and has a hump with shiny, metallic patches on the front and back. . The second generation of comma butterflies overwinter as adults. | | |
| 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...
...g 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. | | |
