A folded alder leaf collected on 3 July 2017 was one of an abundant number in a wooded campground. Most alder bushes contained many folded leaves. Two adult moths emerged, one on the 16th (pictured) and one on the 18th.

A larva was photographed 3 July in situ. One pupa was photographed on 14 July at home. The second moth to emerge was stuck to the pupal case.

Both moths and pupae were saved as specimen # NRBPP-01.

I am at a loss to place these moths in the Gracillariidae, as they were not blotch miners.
