Specimen type: Photograph
Observation notes: Reared from Eurybia divaricata. Feeds on younger leaves as early instars, newer ones are entirely folded inwards. Becomes less picky about leaves as they get bigger. On older leaves, they fold up (onto the upper side of the leaf almost always) part of the margin of the leaf, typically near the base of the leaf and feeds under the small flap. Early instars window mine on the uppersides of leaves within their shelters, later instars eat through the leaf and eat outside and on either side of the shelter mostly. Pupated in the leaf flaps. Five individual larvae were found as early instar larvae as early as 5/10, and they were collected on 5/10, 5/17, 5/19 and two on 5/27. One larva pupated on 6/3, the other four pupated on 6/5. One eclosed on 6/14, and the other four eclosed on 6/17. The first photo is one of the adults that emerged on 6/17. The third photo is a middle instar larva, the fourth photo shows a late instar on the left and a middle instar on the right, and the fifth photo shows an early instar from 5/10. The last photo shows one of the leaf rolls and feeding at the edges of the shelter.
