The Leek Moth (Acrolepiopsis
assectella) larva is specialized to feed on the leaves of various
plants belonging to the genus Allium. In Asia and the U.K the Leek Moth is considered a minor pest.
However, in continental Europe it has caused considerable damage, particularly
to leeks. It was first detected in Canada in 1993 in the National Capital
Region where a local population is now established.
