Slug Caterpillar Moths
More than 20 species in Missouri
Adult slug caterpillar moths are heavy-bodied and furry. The weird-looking caterpillars have suckers instead of prolegs, so they glide around like slugs. Don’t touch — many have stinging spines or hairs.

Eastern Dobsonfly
Corydalus cornutus
Adult eastern dobsonflies are huge and mothlike, with large wings and a weak, fluttery flight. The fiercely predaceous aquatic larvae, called hellgrammites, are well-known to anglers, who often use them as bait.

About Butterflies and Moths in Missouri

Butterflies, skippers, and moths belong to an insect order called the Lepidoptera — the "scale-winged" insects. These living jewels have tiny, overlapping scales that cover their wings like shingles. The scales, whether muted or colorful, seem dusty if they rub off on your fingers. Many butterflies and moths are associated with particular types of food plants, which their caterpillars must eat in order to survive.
