Eggs, larvae, pupae and adults of two aquatic weevils (Euhrychiopsis s
p.3 and Phytobius leucogaster) were found associated with northern wat
ermilfoil (Myriophyllum sibiricum) in the province of Alberta, Canada.
While both weevils had been collected previously in Alberta, this is
the first report to document northern watermilfoil as a native host.
