Illustration of Ant-eating Spider (Euryopis formosa)

The Ant-eating Spider is a tiny, red-and-black theridiid spider that specializes in preying on ants despite the danger involved. It uses silk threads anchored to the ground to trip passing ants, then delivers a rapid, precisely placed venomous bite before the ant can retaliate with its own venom. It is often found living near ant trails.
