Killer Caterpillars 

Tropical islands have always been treasure troves to evolutionary biologists - a trip to the Galapagos largely fueled Darwin's ideas. In Hawaii, researchers have characterized a group of caterpillars that do a couple of things other caterpillars don't do: they eat snails; and they do so by trapping them.

This is really so cool. Like spiders, all caterpillars secrete a sticky substance, but other caterpillars merely use theirs to spin cocoons, whilst clever spiders spin webs to trap prey. This is even cleverer.
