| Rove beetles | Rove beetles (Staphylinidae) are members of the order Beetles. There are about 1,554 species in Germany and about, 47,000 globally. Some examples are: Bledius spectabilis, devil's coach-horse beetle, Ontholestes tessellatus, Oxyporus rufus, Paederus litt...
...re: Bledius spectabilis, devil's coach-horse beetle, Ontholestes tessellatus, Oxyporus rufus, Paederus littoralis, Staphylinus caesareus, Tachyporus hypnorum, Velleius dilatatus and Anthophagus caraboides. The oldest fossil findings suggest that the rove beetle has been in existence for at least 220 million years.
The shape of the rove beetle’s body is very untypical of beetles’ Its body is usually elongated, and the wing covers are shortened, so that the abdomen is unprotected. The advantage of this is that the beetles have greater mobility when entering smallest cavities....
... elongated, and the wing covers are shortened, so that the abdomen is unprotected. The advantage of this is that the beetles have greater mobility when entering smallest cavities. The wings are enfolded by the wing covers. The body length of the rove beetle, (depending on type), ranges from 0.5 to 50 mm and the body is usually black or brown in colour. Occasionally species with a metallic blue-violet or blue colour can be encountered. Other species are very hairy. Most rove beetles are good fliers, and often swarm on warm evenings. While larger species of rove beetle search for food in the night, smaller species are active by day.
Rove beetles can be found in litter and humus in diverse habitats. In the species that live in the deeper layers of soil the eyes are poorly developed and they can not fly. Certain species of rove beetles are found in or on the edge of wetlands, other species, in deserts, mountains or near the polar regions. Most, however, live in the tropics.
The dietary habits of rove beetle larvae are generally the same as the adults. While most rove beetles are predatory some species eat fungi, or putrescent animals and plants. The larvae of some species live as parasites? on the pupaeof flies. There are species of rove beetle, which only inhabit birds' nests, mammals' nests, ants' nests, termites' nests or those of wasps. In ants' nests, rove beetles hunt for their hosts, eat carrion or decimate the hatching ants. Even as migrant guests they are to find amongst hunting ants’ armies where it occurs that they ‘ride’ ants instead of walking. Rove beetle have defence glands, the secretions of which can cause blistering and rashes in humans.
Some species of rove beetle can cause damage to strawberries or fruit trees. However, the rove beetle is enormously valuable for the soil and its remineralisation. Furthermore they eat many insects which are regarded as pests in agriculture and forestry. | | |

| | | Philonthus cognatus | | Philonthus cognatus, (Syn: Philontus cognatus, Philontus fuscipennis) belong to the family rove beetles in the order beetles (Coleoptera), the suborder Polyphaga, the infraorder Staphyliniformia and the superfamily Staphylinoidea. Here - in the subfamily Staphylininae (tribe: Staphylinini, sub-tribe: Philontina) – they belong to the genus Phi... | | |
| | Due to their appearance Philonthus cognatus can be confused with both, representatives of their own genus as well as with other rove beetles. Philonthus cognatus are found almost everywhere in the humus layer of forests, fields, meadows and gardens where they often reside under moss or manure. Their great flexibility allows them access to very small holes, which would be inacces... | | |
| | Anthrenus pimpinellae | | Anthrenus pimpinellae belong to the genus Anthrenus, in the order beetles (Coleoptera), the suborder Polyphaga (water, rove, scarab, longhorn, leaf and snout beetles), the infraorder Bostrichiformia, the superfamily Bostrichoidea (carpet, powder-post and death-watch beetles), the family skin beetles (Dermestidae), the subfamily Megatominae (synonym Anthreninae) and the t... | | |
