Mimosa and Honey Locust (Gleditsia triacanthos)
Life Cycle
Egg laying continues throughout the season. First and 2nd instar larvae spin webs around flowers and leaves then live within these. Adjacent surfaces of webbed leaves may be skeletonized, turn brown, and die. Older larvae feed on the tender, terminal leaves. Some of the 2nd generation larvae pupate in the webbing of infested trees; other larvae pupate in the soil or other protected places.(2)
Larvae live in communal webs and overwinter in the pupal stage (1)

Native to Japan and China first found in the U.S. in Washington D.C. in 1943.
