Hyposmocoma

Hyposmocoma is a genus of moths with more 350 species endemic to the Hawaiian Islands. The genus was first described by Arthur Gardiner Butler in 1881. Most species of Hyposmocoma have plant-based diets, but four species, such as Hyposmocoma molluscivora, eat snails. The caterpillars spin silk, which they then use to capture and eat snails. These are the first caterpillars known to eat snails (or mollusks of any kind).[2]
