Flesh-Eating Caterpillars Discovered in Hawaii

Publication: National Geographic News   Date: July 21, 2005   View Article

In Hawaiian rain forests, scientists have discovered caterpillars with a taste for escargot: They trap snails on leaves using silk webbing and then eat them alive.

These are the first caterpillars known to eat snails or mollusks of any kind, an evolutionary adaptation likely enabled by the island chain’s isolation. The insects are also the first caterpillars known to use silk to ensnare prey in a spiderlike fashion.
