Life Cycle
Overwinter as adults in sheltered dry places. Hibernation can begin in August; eggs are laid in late May or early June, larve begin to hatch in about a week and feed on the undersides of leaves for 2-3 weeks, then crawl down and pupate in bark crevices. There may be 1―2 generations with a partial 3rd generation per year. The first generation is the most injurious.(4)

X. luteola is usually found near places where elm trees have been planted. Trirhabda spp. usually occur in less disturbed areas.
