Recently, an Indo-German research team has discovered 15 species of rove beetles in the waterfalls and forests of Arunachal Pradesh.
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: It is mainly found in sub-tropical, cold tolerant climate.
Habitat: Typical microhabitats include leaf litter, soil surface, under bark, fungi, shorelines, dung, carrion, compost, and nests of social insects;
Diet: These are usually found around decaying animal and vegetable matter, preying on carrion-feeding insects.
Distribution: Rove beetles occupy almost all moist environments throughout the world.
Features:
Some large species are a brightly coloured black and yellow, thus resembling wasps; other rove beetles mimic soldier ants in both appearance and behaviour.
These predatory beetles are beneficial to farmers and gardeners, because they can reduce pest populations, also referred to as biological control
Lifespan is variable: Adults may live ~2 weeks to ~12 months; total life cycle often ~1-24 months depending on climate and species.
It has chemical defenses from abdominal glands; secretions can deter predators and may include irritants or antimicrobial compounds.
