Snail-Eating Caterpillar Discovered in Hawaii:

"The caterpillars inhabit predominantly native wet and rain forests in the Hawaiian Islands and maintain a strict diet of native snails. They are very specific eaters and will not accept foliage, even if starving. Because the snail’s shell presents a challenge, the caterpillar has learned to utilize its silk in a spider-like fashion to immobilize its prey. Although all caterpillars have the ability to produce silk to form cocoons, this is the first record of a predatory caterpillar which uses silk to catch live prey."
