Description: The rove beetles (Staphylinidae) are primarily distinguished by their short elytra (wing covers) that typically leave more than half of their abdomens exposed. With roughly 63,000 species in thousands of genera, the group is currently recognized as the largest family of beetles. In Europe, more than 2,000 species are listed.
The Imperial Rove Beetle is a relatively large rove beetle of 17-25mm length. The elytrae are red. It wears golden hairs on the abdomen and on the temples.
Biology: These beetles hunt the fly larvae on excrement and decaying plants . The elongate larvae are hidden underground and from their hole, they capture insects that pass nearby.
The eggs are laid in the ground at shallow depth. The larvae rapidly hatch and molt three times before pupate in a small hole underground. Adults appear in spring. The total development lasts 2 to 3 months, in one generation per year.
Habitat: Roadsides, forest edges; common species in low mountains.
Distribution: Central and Southern Europe, Western Asia.
