Epomis Ground Beetle
A beetle whose larvae lure and devour frogs — a rare case of predator-prey role reversal. The larva waggles its antennae to attract an amphibian, then latches on and feeds.
Did You Know?
This is one of the only known cases where an insect larva regularly preys on vertebrates — the larvae have a near 100% success rate against attacking frogs.
European Trechus Cave Beetle
A small, pale brown ground beetle with four prominent striae on each elytron. Despite belonging to a subfamily with many cave species, this species is a common surface dweller in Europe.
Did You Know?
It is one of the most widespread ground beetles on Earth, having been accidentally introduced to every continent except Antarctica through human trade and agriculture.
