The lace bug Leptoypha mutica, a specialist on trees and shrubs of the Oleaceae, feeds mainly on ash, Fraxinus spp., and fringetree, Chionanthus virginicus. In July 1987 and 1988, nymphs and adults were observed on late lilac, Syringa villosa, in a landscape planting in northwestern Pennsylvania. Infested leaves showed chlorotic blotches, the damage concentrated around midribs and lateral veins. This is the first report of lilac serving as a host for a North American tingid.
