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 appear from June to July and from August to May in the following year. They live (two generations at once) in a web on the upper side of the leaves of their food plants (including lichwort, comfrey and stinging nettle), and eat the leaves down to the skeleton. At the end of their development, the larvae pupate in a thick, white cocoon inside a leaf or near the veins on the leaf surface, causing the leaf to roll ... | | |
| | | Root-maggot flies prefer to live on flowering plants, where they feed on the nectar and pollen. However, they also sometimes feed on liquid manure, sweat, blood or the watery discharge from wounds. Some species live on rotting seaweed, others reside in the nests of bees or wasps, where they eat the f... | | |
| | The fertilized females lay their eggs on the host plants of the larvae, or in the soil. The larvae feed as rootworms or mostly as leaf miners. Some species of larvae can cause considerable damage when they infest crops. This includes in particular, species of the genus Delia (Delia antiqua, Delia coarct... | | |
| | Anthomyia pluvialis are active from May to October. The males are often encountered in groups in the shade of trees. The adult flies feed on nectar and pollen from flowering plants, the females suck the blood of other insects or conspecifics. | | |
| | Adult Stictoleptura cordigera visit flowering plants, especially Umbelliferae (Apiaceae). The larvae of the beetle develop in the decaying wood of deciduous trees. | | |
| | The females use ovipositors to lay their eggs in small cracks or holes in their larvae’s food plants. The larvae of longhorn beetles are pure herbivores. They mainly feed on wood. Their bodies are flat when they live under tree bark and cylindrical, when they bore into the interior of the tree. Some species specialize in dead wood. Heartwood eati... | | |

Egg laying takes place in several sessions on the food plants of the larvae. The females attach each of the 100 to 600 oval, light to egg yolkyellow coloured eggs to the underside of leaves, in batches of 20-45. In its entire life cycle a female produces about 1,200 eggs. | | |

| | Mature larvae are able to secrete a substance which drives away their competitors ,especially adult beetles of the same species, from the leaves of the forage plants. At the end of the third larval stage, the larvae dig down into the soil to a depth of about 2cm and pupate. After 6-9 days the adult beetles hatch from their pupae. They have a flight radius of about 10 metres. In late autumn they begin eating ... | | |
