Here are two Caloptilia species which have visited the lights, both in June 2004. Members of this genus are leaf miners... the caterpillars feed between layers of leaves. Of course, this means that they are very tiny. The adults have a characteristic resting posture (as seen here) with the front of the body held well above the horizontal. Also notice the shield-like projections on the forelegs. Any help in IDing these guys to species would be greatly appreciated.
