April 6, 2026

Researchers have discovered three previously unknown species of rove beetles in Arunachal Pradesh, marking a significant addition to the state’s rich biodiversity.

About Rove beetle:

  • Rove beetles (family Staphylinidae) are one of the largest beetle families.
  • Appearance: They are typically elongate, fast-moving beetles with shortened wing covers (elytra) that expose flexible abdominal segments.
  • Many species of these beetles can raise the abdomen in a scorpion-like defensive posture (not a true sting).
  • Preferred climate: sub-tropical, cold tolerant
  • Distribution: Rove beetles occupy almost all moist environments throughout the world.
  • Habitat: Typical microhabitats include leaf litter, soil surface, under bark, fungi, shorelines, dung, carrion, compost, and nests of social insects;
  • These are usually found around decaying animal and vegetable matter, preying on carrion-feeding insects. 
  • Features:
    • These predatory beetles are beneficial to farmers and gardeners, because they can reduce pest populations, also referred to as biological control
    • Chemical defenses from abdominal glands; secretions can deter predators and may include irritants or antimicrobial compounds
