Lace bugs are whitish sucking insects with broad gauze-like or lace-like wing covers. Various species attack a number of trees and shrubs; species that attack forest trees include sycamore, oak, basswood, elm, and hackberry lace bugs.
Lace bugs live and feed on the undersides of leaves, often leaving them speckled with eggs, excrement, and the cast skins of developing nymphs. The upper surfaces of infested leaves may appear whitened, brownish, or dead. The leaves of heavily infested trees often turn brown and fall. Lace bugs overwinter in either the adult or egg stage. Most species have two generations per year.
