| Adult Tachina fera feed on the nectar of flowering plants and on honeydew, while their larvae live off the body tissue of different caterpillars. The females lay their eggs near the caterpillars. The larvae immediately hatch from their eggs and penetrate the host caterpillars. The caterpillars die because the larvae feed on their inner tissue. The larvae are parasitic on the caterpillars of the gypsy moth (Lymantria dispar), the black arches (Lymantria monacha), and the pine beauty (Panolis flammea). | | |

A clutch comprises approximately 50 to 200 eggs. The young caterpillars, which hatch after a few days, are gregarious and live in self spinned tissue. At the end of the larval period, lasting 1 to 2 months, they are living solitarily or in small groups. The caterpillars then pupate. The pupae are brown or light green with shimmering patches and are covered in spines. 12 days after pupating the small tortoiseshell butterfly hatches. Parasitic Diptera pose a threat to the caterpillars. Birds eat the pupae, but not the caterpillars. | | |
| | | 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, it’s about two weeks until the new butterflies hatch. | | |
| 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 b...
...hat 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. | | |
| | Painted lady caterpillars reach lengths of 35-40 mm. Their bodies have a light yellow to greenish-brown base colour. On the surface, a fine, dark pattern can be discerned, which varies in form. The caterpillars have a shape like a ring and branching spines on each segment of their bodies. The rings lie between the spines and are (like the entire back) usually more yellowish, while the base of the spines is more reddish. Other caterpillars of the same species are much brighter, with a high proportion of white. | | |
| The caterpillars of the last generation overwinter. They pupate in spring of the following year and emerge as adult butterflies in May. The adult brown argus butterflies are active from May to June. During this time they mate and reproduce. The fertilized females al...
... to June. During this time they mate and reproduce. The fertilized females always lay their eggs on the host plants of their larvae, on the underside of the leaves. The development from egg to caterpillar takes about 10 - 12 days. After hatching the caterpillars immediately begin feeding on the host plants and after about 60 days they have completed their development. They are greenish and have a pale line lengthwise on each side. When they have reached a length of about 20 mm they pupate. They hatch from t...
...eted their development. They are greenish and have a pale line lengthwise on each side. When they have reached a length of about 20 mm they pupate. They hatch from the pupae from late July to mid September and produce the second annual generation of caterpillars which overwinter in leaves in frost free places. | | |
| It feeds on nectar from thistles and cornflowers. In May or June the females lay about 100 to 300 eggs in groups on the host plants, on the undersides of the leaves. The caterpillars hatch after about 2 weeks and are yellowish-green and spotted black. They eat in groups. The older larvae are solitary. The caterpillars can be encountered from June to October and reach lengths of up to 40 mm. They develop a clear warning sign, and are equipped with a chemical defense system which is based on sulphur compounds and derived from the forage plants (various types of cab...
...ngths of up to 40 mm. They develop a clear warning sign, and are equipped with a chemical defense system which is based on sulphur compounds and derived from the forage plants (various types of cabbage, milkwort, nasturtium). After 3 to 4 weeks, the caterpillars pupate, often after long hikes in search of suitable sites. | | |
| | Map | | ...is a butterfly species in the family Nymphalidae. There are two generations a year whose adults look significantly different. The reason for this is to find in the different day lengths (sunrise to sunset) during the development of both generations’ caterpillars. The reason for this is the differing amounts of daylight available during the caterpillars’ development. The name of the butterfly is derived from the marking on the underside of the wings, which resembles a map. This butterfly is found in Europe, Central Asia and Japan. It is beginning to spread to Scandinavia and the Baltic States. | | |
| | Lepidopterans begin life as caterpillars. They hatch from eggs and feed on plants before they pupate. After their metamorphosis, they hatch from their pupae as an adult butterfly (imago) to live on and store new eggs. Lepidopterans and caterpillars are able to camouflage themselves using colour and texture and even practice mimicry. | | |
| | The small white feeds on the nectar of various flowering plants. The females lay about 150 eggs on the food plants of their caterpillars - Cruciferae, cabbage, Reseda, cress, mustard and radish - which hatch after a maximum of 8 days. The caterpillars are solitary. After moulting four times they pupate. If the pupae do not hibernate, the new butterflies emerge after 10 days. The small white produces 2 - 3 new generations a year. | | |
