Last season, the unusual leaf symptoms caused by the Redbud Leaffolder (Fascista cercerisella; order Lepidoptera; family Gelechiidae) on its namesake host were observed throughout Ohio. Questions regarding leaves turning brown after being folded over or "glued" together continued to come into Extension offices throughout September. This could be a repeat season based on what I've seen so far.
Two-to-three overlapping generations occur per season in Ohio with 2nd and 3rd generation nests containing caterpillars in various stages of development. Populations tend to build with each generation and it appears we are well into the 2nd generation in many areas of the state. The moth spends the winter as pupae in debris and fallen leaves beneath infested trees.
