Hyposmocoma molluscivora is a Hawaiian moth whose larvae are predators, capturing snails in their silk, much like a hunting spider's web, and then crawling inside the snail's shell to eat it alive.

They are case bearing moths, spinning a loose shell of their own which they carry around with them as protection, like bagworms.

The specific snails they eat are of the Tornatellides genus.

The caterpillars, which live exclusively on the islands of Maui and Molokai, are about 0.3 inches (8 mm) long, and sometimes decorate their silk case with actual snail shells, perhaps as camouflage.
