Lesser searcher beetle

Calosoma inquisitor

The lesser searcher beetle is a shiny ground beetle that is a real caterpillar hunter. Unlike many ground beetles, it flies well and climbs up into bushes and trees to search for food. When it feels threatened, it lifts up its front and opens its jaws wide.
