University of Illinois Extension - Selecting Trees for Your Home
Severity: 2 out of 5
Frequency: 3 out of 5
Symptoms: Leafrollers in general are solitary and web a leaf so that the leaf appears rolled or folded. Once the leaf is rolled, the insect feeds inside. The rolled/webbed leaf also offers the leafroller some protection from predators as well as insecticides. In severe cases, individual leaves will turn brown or lace-like due to the feeding of the caterpillar.
Cycle: After the caterpillar pupates in the rolled leaf, the adult moth emerges to mate and lay eggs.
Management: Usually damage is too scattered and slight to warrant control.
