The caterpillars are gregarious and live on their forage plants (Violaceae, Urticaceae, Ulmaceae, Salicaceae, Cannabaceae, Caprifoliaceae or honeysuckle family etc.). When they want to pupate, they attach themselves to plants and other structures and hang from them... | | |
| | ...ek out the food plants of the larvae where they lay their eggs on the upperside of the leaves. The eggs are shaped like a cone, grooved, and greenish-grey in colour. They remain on the leaves for 3 to 5 days before the larvae hatch. When the larvae (caterpillars) have hatched, they build a tissue on the leaf, which initially covers the tip and then the whole leaf, under which they can eat undisturbed. The web, however (as in the case of thistles) between leaf growth and stem can be mounted. | | |
| | The nettle-tap moth is diurnal. The first generation are active from early May to early July and the second from late July to early October. These moths are found in all habitats where nettles (Urtica) especially Urtica dioica, grow. The caterpillars of the nettle-tap moth reach body lengths of about 10 mm. The body surface is finely ridged, pale yellowish-green to whitish-green, sometimes translucent, and therefore darker in the front half because here the internal organs show through the ski... | | |
| | 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... | | |
| | Adult european hornets’ main tasks are brood care, protection of the nest against enemies, and the hunt, both by day and night,for insects such as flies, wasps, bees, moths, grasshoppers, beetles, caterpillars or Odonata to feed the queen or the larvae. They themselves feed on tree sap , plant juices, nectar, fruits or honeydew. In autumn the young queens and drones hatch. In late September or early October the drones start fightings between themselves ... | | |

The Silphidae and their larvae live and feed on carrion - necrophagous, on parts of plants - phytophagous, on faeces - coprophagous, or by preying on adult insects, insects’ larvae or on snails. Dendroxena quadrimaculata live off caterpillars, while members of the genus Nicrophorus bury the corpses of small animals (mice, moles etc.) and dig an incubator for oviposition alongside them. The females form small balls out of the dead tissue with which they feed the larvae after hatching. Be... | | |
| | Moths and Butterflies are of great importance as bio-indicators and plant pollinators. Caterpillars, butterflies and moths have a large number of enemies. Many lepidopteran species are endangered, although this is mainly due to the increased use of pesticides in agriculture. | | |
| | ... long ovipositors, which can differ in length even within a species. The great length of the ovipositor, up to fourteen times the actual body length, is required for egg laying, which is often done by boring holes through leaves into the interior of caterpillars, which can have long spines or bristles for protection. An important characteristic of braconids is the rigid connection of their 2nd and 3rd abdominal segments. | | |
| | Two-tailed pashas prefer to live in habitats in which strawberry trees (genus Arbutus) grow. This is the food plant of their caterpillars. The adult butterflies live on rotting fruit, excrement and sweat and can fly well and fast. They can be watched in their flights for hours. Male specimens of two-tailed pasha guard their territory and fend off competitors from the same species. Occ... | | |
| | ...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. | | |
