The Imperial Kurzflügler ( Staphylinus caesareus ) is a beetle from the family of the Kurzflügler (Staphylinidae).
General
Imperial Kurzflügler grow to be about two centimeters long. The head, thorax and abdomen are colored black. The label is hairy black, at most in the front corners with individual yellowish hairs. The elytra , which cover only a third of the abdomen, are red. The same applies to the legs and antennae. The physique is very slim overall. Almost the whole body is covered with fine hair. The abdomen bears a golden yellow patch of hair on each side of the base at the rear edge of the tergite . The well-developed jaw forceps are also striking . Staphylinus erythropterus is similar , but in this case the label is hairy golden yellow, the 2nd and 3rd tergites are completely black without a golden yellow hair spot.
The beetles are particularly widespread in southern Central Europe. The animals can be found in forests, where they stay on the ground.
Imperial short-winged birds hunt for insect larvae and nudibranchs on the forest floor, which they can easily grab with their upper jaws. Thanks to the flat body, the animals crawl into very narrow cracks and crevices. The beetles are able to fly; The correct wings are hidden under the cover wings. In the event of imminent danger, the rhinoceros spread its jaws and stretches its abdomen forward to intimidate the enemy. The larvae are similarly predatory as the adult animals. After skinning three times, the animals pupate in a mummy doll . The finished beetle then hatches from this.
