Geotrupes stercorarius reach lengths of 16 mm to 25 mm. The face of the beetle is black or black-blue, and the underside is blue, blue-green or blueviolet. The beetles are slightly hairy. Their wing covers each have 7 long rows of weak spots. The beetle can make noises. with its rear hips.
The beetle prefers to live in forests. The adults fly at night close to the ground making a loud humming sound. In the spring males and females dig a 40 cm long underground tunnel for mating, which leads into several chambers, which can be reached through tem... | | |
| Water scavenger beetles reach body lengths of 4-9 mm. Their bodies are oval-shaped, with a very flat underside. They have a slightly metallic sheen, are deep black in colour and shimmer slightly bronze when seen in light.
Adults have short, club-shaped antennae. The...
...e antennae often have dark ends. On the wing covers (elytra) are 10 stripes of fine, puncture-like points. These stripes, which are lengthwise and become furrow shaped at the rear end, are the main distinguishing feature of the water scavenger beetle. Additional rows from irregular posited series of points appear in the space between the rows from regular posited points. The legs of the beetle are yellowish, yellow-brown or rust-colored. The tarsi appear reddish brown to dark brown in colour.
The hind legs have long hairs that aid in swimming. The water scavenger beetle prefers to live in and on smaller bodies of waters with sufficient sunlight. They are often found (as adults or larvae) floating on the surface of salt water or brackish water (mixture of river and sea water). The adults eat rotten plant debris....
...head first and trap air to breath under their wing covers (elytra) and "row" themselves along by alternating the hind legs, wiggling from side to side as they swim. Their eyesight is not very developed. Therefore, it is possible for the beetles to land on? reflective surfaces (wet or shiny car roofs, windows, etc.) having confused them with open waters.
After mating, the oviposition of the females happens in cocoons near the surface of water where the eggs are glued to water plants. A... | | |
| | Brassy willow beetle | | The brassy willow beetle (Phratora vitellinae) belongs to the order beetles (Coleoptera), suborder Polyphaga, infraorder Cucujiiformia, superfamily Chrysomeloidea, family leaf beetles (Chrysomelidae), subfamily Chrysomelinae, tribe Phratorini and the genus Phratora. Scientific synonyms include: Phyllodecta vitellinae and Pharatora vitellinae. The brassy willow beetle is commonly encountered throughout Europe.

| | All beetles use virtually any organic food source however the larvae have a completely different diet to the adults. Beetles can be classified according to what they eat. There are two types coprophagous and necrophagous. The former feed on excrement (earth-boring dung beetles) and the latter on carrion (Silphidae).
The excretions of both species are from great importance at the remineralization of the soil. Beetles, like all living creatures, are dependent on water. There are species that live under or near the water like hygrophiles or predaceous diving beetles.
Depending on which species they are, beetles fly shorter or longer distances. There are also species that are not capable of flight because (as is the case for most ground beetle species) their wings are missing. There are beetle species producing sounds by moving parts of their bodies. Some beetles are able to generate light (such as fireflies). | | |
| | | Chrysolina sanguinolenta | | The Chrysolina sanguinolenta is a member of the leaf beetle family. It is commonly found in Europe and Asia.
This beetle can reach lengths of 6 to 9 mm. Their bodies are dark. The wing covers have a red edge and rows of points. The wing color is pink.
The main food of the Chrysolina sanguinolenta is the Common Toadflax.

| | European rhinoceros beetle | | The European rhinoceros beetle (Oryctes nasicornis) is a species in the order beetles (Coleoptera), the family Scarabaeidae, the subfamily Dynastinae, and the genus Oryctes. This species is widespread in Europe, North Africa and Southeast Asia. | | |
| | ...larvae slip off after a few days and eat up to 1200 aphids during the two weeks of their development. The larva turns into a pupa on a leaf. After about one week the adult Asian ladybird slip off the pupa.
At the production of wine the Asian lady beetle can be a problem. The hemolymph of the beetle affects the taste so dramatically, that the wine is unfit to drink.
Asian ladybirds are commonly found in populated areas, where they seek out (often in large numbers) apartments and houses to hibernate , and can thus be a pest. | | |
