Recorded by: Tracy S. Feldman on 2017-05-09 Durham Co. Comment: An occupied mine on Oenothera fruticosa. An adult emerged about 21 days later (see companion photo).
Recorded by: Tracy S. Feldman on 2017-05-09 Durham Co. Comment: A view of leaf mines on Oenothera fruticosa--larvae make more than one mine before pupating. The mines span the upper and lower surfaces, and have trails of frass. The larvae are pink-orange. An adult was reared from one of these larvae (see companion photo from 2017-05-31).
