Parapoynx allionealis
Watermilfoil Leafcutter Moth
Parapoynx allionealis, commonly known as the watermilfoil leafcutter moth, is a crambid moth native to North America. The species is notable for its aquatic larval stage and its specialized feeding on submerged and floating aquatic plants. It has been documented across a broad geographic range spanning eastern and central North America, from southern Canada to the Gulf Coast. The common name reflects its association with Myriophyllum (watermilfoil) species, though larvae feed on multiple aquatic plant genera.
