Littoral whiplash rove beetle
The littoral whiplash rove beetle is a distinct beetle recognizable by its elongated body and the bright, metallic sheen that often adorns its elytra, a hardened pair of forewings. Famed for its unique defensive chemical arsenal, this beetle can secrete a potent irritant called pederin. While primarily carnivorous, its diet varies with its life stages, feeding on smaller arthropods as an adult, and consuming a wider variety of organic detritus during its larval phase.
