Range

Food

Life Cycle
Remarks
"Of the above-mentioned plants, Brasenia, Nuphar, and Polygonum are normal hosts. Populations feeding on Myrica may eventually be proven to belong to a separate species. In fact, beetles historically recognized as G. nymphaeae may well represent several sibling species, with true G. nymphaeae not occurring in North America at all. Whatever the case, beetles are apparently sometimes so numerous that they leave their normal hosts and may temporarily feed on other plants. Even so, some of the recorded associations were probably purely incidental." (3)
