Identification

Technical Description, Adults: Neunzig (1996)

Adult ID Requirements: Identifiable from good quality photos of unworn specimens.

Immatures and Development: The larvae appear to specialize on species of Gleditzia. Neunzig (1979) summarized the life history based on earlier studies by Comstock (1881) and Packard (1890), who noted that there can be several generations per year. The final seasonal generation overwinters as pupae in the soil, with the adults emerging after the spring leaf-out. The first-instars are leaftiers that bind two opposing leaflets together and skeletonize the tissues within. The shelters often have small whitish or brown necrotic areas on the outer surface of the leaves that form the shelter. With time, more leaflets are incorporated into the structure. These are left attached to the rachis and a silken tube is often produced within the structure along the rachis that binds to the leaflets. The older instars often cut and eat entire leaflets, which can cause defoliation either locally, or for the entire tree, depending of the degree of infestation. The final-instar larvae cut and attach several leaflets to their feeding structure, then pupate within the rather bulky brownish shelter. Larvae in the final seasonal brood drop to the ground to pupate and overwinter. Neunzig (1979) noted that small larvae in North Carolina first appear on the foliage in April, while late-instar larvae typically drop to the ground in September and enter the soil to pupate.

The larvae have a greenish body with a series of faint yellowish or yellowish-white longitudinal stripes, with those along the lower sides being most prominent. The head and prothoracic shield can vary from predominantly whitish in early instars to more amber-colored with darker mottling in the older instars. Older instars range from around 12-20 mm in length.

Habitats and Life History

Habitats:

Larval Host Plants: The larvae appear to special on species of Gleditsia, including Water Locust (Gleditsia aquatica) in Florida and Honey Locust (G. triacanthos) elsewhere throughout the range (Forbes, 1923; Prentice, 1966; Neunzig (1979); Godfrey et al., 1987; Heppner, 2007; BugGuide). In North Carolina, all of our larval records are from Honey Locust. - View
