Abstract: Crosson Euhrychiopsis lecontei (Dietz) is a small native weevil that feeds on various species of watermilfoil. Its natural host is northern watermilfoil (Myriophyllum sibiricum Komarov); however, it has been shown to feed extensively on Eurasian watermilfoil (Myriophyllum spicatum L.). The ability of this insect to feed on and damage Eurasian watermilfoil has led to its use in the management of this nonindigenous plant.
