This insect is about ΒΌ inch long. It is reddish/yellow on its head near the eyes with dark markings. The insect lives on basswood and oak leaves. The larva mines the leaves feeding between the upper and lower surfaces. Although injuries produced by leaf mining insects can be unattractive, it is rare for them to affect the plants health. If damaged by insects the leaves will have a hollow area and that may be open. Then a Leaf spotting fungi can cause these open areas to collapse, without any tunneling.
