Trechine Cave Ground Beetle
A fully cave-adapted ground beetle from the Pyrenees with no eyes, no pigmentation, and extremely elongated spider-like legs and antennae. It is beautifully adapted to life in total darkness.
Did You Know?
Named after Cerberus, the three-headed guard dog of the underworld, this beetle navigates pitch-dark caves using enormously elongated antennae that can be twice its body length.
Green Tiger Longhorn
A medium-sized Neotropical cerambycid with silvery-green pubescent patches on a dark body, found in the Atlantic Forest of Brazil. It breeds in dead branches of native hardwoods. Adults are diurnal and visit flowers.
Did You Know?
The silvery pubescence is formed by flattened scales that reflect light, giving the beetle a shimmering appearance.
