genus
Parapoynx
“Aquatic Caterpillars, Snout Moths”
Genus Overview
There are 7 North American species of this genus. Larvae of Parapoynx feed on pondweed (Potamogeton), watermilfoil (Myriophyllum), waterhyssop (Bacopa), eelgrass/tape grass (Vallisneria), and broadleaf plants such as yellow water-lily (Nuphar), water lily (Nymphaea), water-shield (Brasenia), floating-heart (Nymphoides), golden-club (Orontium), and other freshwater species. They often cut circular pieces from the edges of broadleaf species to cover themselves while feeding on the tops of the leaves, other times drilling from the top of the stem downward. Pupation occurs in a silk-lined chamber under the leaf patch or in the plant stem.
