Lesser searcher beetle

Lesser searcher beetle

Calosoma inquisitor

A species of Caterpillar hunter beetles, Also known as Caterpillar-hunter

The metallic sheen of lesser searcher beetle glistens as it moves nimbly on the ground, a visual hallmark of its hunting prowess. Unlike many of its relatives that take to the air, lesser searcher beetle prefers terrestrial hunting, relying on its acute vision to locate prey. Its diet is notably diverse, ranging from soft-bodied invertebrates in earlier life stages to a more carnivorous diet as an adult, where it becomes a voracious predator of caterpillars and other garden pests.
