2.  Honeylocust Pod Gall Midge
Green, globular, podlike galls, 1/8 inch in diameter, develop on new leaflets in spring and early summer. The galls turn reddish, then brown, and many of the infested leaflets drop. Twigs or branches sometimes die back after several years of infestation. One to several whitish larvae, ¼ inch long, are feeding inside the gall.
