Mimosa Webworm

Mimosa webworm damage on honey locust branches.

Mimosa webworm damage is becoming apparent on honey locust throughout the state and on silk tree or mimosa in southern Illinois. The second generation of this insect webs several compound leaves together and then window-feeds on the leaves, causing the leaves to turn brown. This damage is obvious when the webworm is numerous. Refer to Issue 6, the June 5, 2017 issue of this newsletter for additional information on life cycle and management. (Phil Nixon)
