Life History
The honeylocust plant bug overwinters as an egg. The eggs hatch just after the vegetative buds of the honeylocust begin to open. Young nymphs beginning feeding with the most serious damage occurring at this time. Feeding by the nymphs causes a death of leaf cells particularly on the immature leaves. Nymphal development requires approximately 30 days with adult appearing by late May and early June. Eggs are laid by the adults in linear clusters under the bark of 2 and 3-year old twigs. The eggs then overwinter. There is one generation per year and the adults usually disappear by mid to late July.
