Weaver ants swarm across the top of a leaf in Sri Lanka, while the mimic jumper Myr marachne(with her fake ant-eye spot and fake ant antennae forelegs) hides under it. She doesn't fool the ants; they operate on smell, not sight, and would eat her in a second if they could. She fools those predators who avoid toxic, nasty-tasting ants. Another mimic (far left, at center) moves and looks antlike, until you count the legs. Other jumping spiders, the wolves of their kind, hunt ants. This Singa pore jumper (left, above) has just dis patched one. Yet even ant-eaters can be confused. A black jumper in Australia (left, below) mistakes an ant-mimic jumper for the real thing.
