Observation notes: Found as completed upper surface linear blotch mines on Toxicodendron radicans. This individual was a solitary miner, but these mines were common on posion ivy, and while this one was found already pupated, others looked very young/new with very small white circles that over the past few weeks have grown significantly. Some leaves had mines that appeared to have up to about 3 pupal chambers. The creases in the epidermis demarcate where there is a pupa in the image below. The adult emerged 9/10.
