| The larvae hatch in spring (April or May), although the timing depends on the weather. They feed on the same plants as the adults. Their upper body is covered with spikes of different lengths, which sometimes split into two. The lattice-like structure on the surface of the body (which is characteristic of the species) is not yet apparent on the bodies of the larvae. Like the adult bugs, they are covered with waxy secretions from their glands which make their surface look powdered. The development of the larvae takes place ... | | |

The bug is oval in shape and can reach lengths of 3.8 to 5 mm. Their antennae are about the same length as their bodies, and are bright and clearly segmented. The upper side of the body is bare and shiny. Half blankets and neck shield have a dark brown to black hue and the centre and tips of the wings bear patches of yellowy - red. On the upper side of the insect is a yellow mark in the shape of a small heart. These bugs have la...

The body is constructed like that of other insects. The head is equipped with compound eyes, antennae and a proboscis. It is followed by the chest (thorax) with the wings, which characterise the shape of lepidopterans. Finally there is the abdomen. Lepidopt...
...ted like that of other insects. The head is equipped with compound eyes, antennae and a proboscis. It is followed by the chest (thorax) with the wings, which characterise the shape of lepidopterans. Finally there is the abdomen. Lepidopterans reach body lengths of 1.5 - 100 mm. The largest lepidopteran species is native to South America and reaches a wingspan of 300 mm, while the smallest lepidopteran wingspans are 1.5 - 2 mm. | | |

| ...he 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 skin. Their breathing holes are very small and have a brownish periph... | | |

| Philonthus cognatus reach body lengths of 8-11 mm. Their elongated and partially hairy bodies are primarily black. The front section of their body has a greenish bronze shimmer. The rounded head is black with a dark green to bronze shimmer. The first segment of the antennae is yellowish in colour on the underside and black on the upper surface, while the following ten segments are entirely ... | | |

| The common cluster fly is medium-sized, reaching body lengths of 4.5 to 12 mm. Its body is brownish-black. Its head is whitish-grey and it has a dark marking covered with black bristles in the middle of its face. The eyes, which are on top of the head and nearly touch, are compound, large, oval and reddish-brown in colour. | | |
|
| Silphidae reach body lengths of 4 - 40 mm. The species with the largest specimens belong to the subfamily Silphinae. The bodies of Silphidae vary according to species and may be flat (subfamily Silphinae), elongated (subfamily Nicrophorinae) or oval. The basic body colour of most Silphidae is black or dark brown. Some species have reddish stripes or patches on their wing covers (elytra.) Some Silphidae are yellow and have black spots. | | |

| Egg-laying (up to several hundred eggs in a lifetime) is done with an ovipositor in moist soil orin the mud at the bottom of a body of water. The larvae reach body lengths of about 50 mm and live on plant roots, which they eat. They pupate in the soil or in rotten wood. Crane fly larvae can cause significant damage to crops. | | |
|
Adult specimens can reach body lengths of 5 to 9 mm. Including their long (and hairy) tail appendages total lengths of 8 to 17 mm are possible. Their long and slender bodies are yellowish-brown in colour sometimes with a green shimmer. The head is light coloured with a centra...
.... 7 pairs of gills are located laterally, the first six pairs of which work almost continuously. At the end of its abdomen it has 2 long and hairy (whitish and filamentary structured) tail appendages (Cerci), which are much longer than the entire body. The front wings are crystal clear (like glass) and have very noticeable dark veins. The rear wings are missing. | | |
|
| Adult Pear Sawflies can reach body lengths of about 5 mm and wingspans of up to 10 mm. Their bodies are uniformly black in colour. The larvae are club-shaped, tapering towards the rear end of the body, and are about 10 mm in length. The larvae are initially white, later yellow to yellow-green in colour and are covered with an ink-like, smelly, shiny-black layer of mucus until the end of the penultimate larval stage. This protects them from predat... | | |
