	abstract = {Eubrychius velutus (Beck, 1817) (Coleoptera, Curculionidae, Ceutorhynchinae, Phytobiini) is an aquatic weevil distributed throughout Europe and Asia. It is closely related to Euhrychiopsis lecontei (Dietz, 1896), which is native to North America and is a potential biological control agent of Eurasian watermilfoil (Myriophyllum spicatum L.). Both weevils are watermilfoil (Myriophyllum) specialists and complete all life stages submersed on the plants. We describe and illustrate the life history of Eubrychius velutus and compare it to Euhrychiopsis lecontei. Both species have very similar life histories and developmental performance. However, Eubrychius velutus develops in the meristem and outer portions of the plant and pupates in a cocoon on the top 5 cm of the plant, whereas Euhrychiopsis lecontei larvae mine the stems and also pupate there. Developmental rates and survival of Eubrychius velutus were very similar to developmental rates of Euhrychiopsis lecontei. At 23 [degree]C, eggs hatched in three days, larval and pupal development each lasted about 10 days and total development from egg to adult was completed in 23 days.},
