Long-horned Ant-loving Beetle
A minute, blind pselaphine rove beetle with elongate antennae relative to its body size. Like its congeners, it is an obligate myrmecophile entirely dependent on host ants for nutrition.
Did You Know?
The elongate antennae of this blind beetle serve as its primary sensory organs for navigating the total darkness of its underground ant-nest home.
Stridulating Passalid
A large, shiny black bess beetle with prominently punctate-striate elytra and strong mandibles. It lives in family groups within decaying logs. Known for producing a wide repertoire of stridulatory sounds for communication.
Did You Know?
Adults produce sounds by rubbing specialized ridges on the abdomen against the underside of the wings, creating at least 14 distinct calls.
