Corythucha arcuata (Say, 1832) - (oak lace bug)
This lace bug attacks oak trees, and some other plants like chestnut trees. It is native to North America and has been accidentally introduced into Europe. It was first recorded from Italy in 2000 and has since spread to other parts of Europe and western Asia. The bugs suck the leaves and heavy infestations cause discoloration and premature leaf drop. Outbreaks have been reported in the invaded areas.
Female lace bugs start to lay black, elongated eggs in spring on the underside of leaves. One generation is completed in about 1 month to 6 weeks and there are 2-4 generations per year. The adults are around 3 mm long and overwinter in the cracks of the bark or in leaf litter.
