Lace Bug now prevalent in Northeast Ohio

June 1, 2008 - Observed activity of overwintered HAWTHORN LACE BUG (Corythucha cydoniae) and OAK LACE BUG (C. arcuata) adults laying eggs on the leaves of their namesake hosts in central Ohio. Like most lace bugs, hawthorn lace bugs live on the underside of leaves. They have a cosmopolitan palate and may be found on several species in the Rosaceae family including cotoneaster and Amelanchier as well as hawthorn. Oak lace bugs focus their attention on their namesake host, but they are particularly fond of oaks in the white oak group. These oak lace bugs are unusual in that they live on the upper leaf surface.

Both Hawthorn Lace Bugs and Oak Lace Bugs use their piercing/sucking mouth parts to suck juices from their host plants. Their feeding produces tiny yellow or whitish leaf spots (stippling) that may coalesce to produce large, yellow-to-copper colored areas on leaves, and early leaf drop. Lace bugs also deposit unsightly hard, black, varnish-like tar-spots of excrement onto the leaf surface as they feed. The bugs have multiple generations per season, and their damage builds with each succeeding crop of bugs. It is important to closely monitor and control lace bugs early in the season to avoid the collective damage produced by successive generations.  Call to have your plants protected now…..
