Family: Chrysomelidae

Reed Beetle

There is one common Chrysomelidae genus in Minnesota waters: Donacia. Donacia looks like a Lepidoptera caterpillar, but it does not have prolegs with crochet hooks (click to compare with Lepidoptera). The Donacia body is unsclerotized and obese, with 3 pairs of segmented legs on the thorax. The main identifying character is the two large sclerotized hooks on the ventral side of the end of the abdomen.
