Orchestes fagi (Linnaeus 1758) - (beech flea weevil)
This weevil is native to Europe and feeds on the young leaves of beech and other trees. In Europe it can cause occasional outbreaks on beech and also on apple. Young fruits of apple and cherry might also be damaged. Since 2011, the weevil has been recorded from parts of eastern Canada and has caused defoliation of beech trees in some areas. Although the weevil is polyphagous in Europe, it apperas to be restricted to beech in Canada (Moise et al., 2015).
Adults create holes in the leaves and the larvae mine the the midribs and later the leaf blades. The damage can cause leaf drop. Adults overwinter in the bark or in the soil. The adults are 2½-3 mm long, dark brown to black and covered with gray hair.
