Aspilanta oinophylla

[1][2] In its native range, A. oinophylla can be found in Canada (Ontario and Quebec) and the United States (Connecticut, Georgia, Kentucky, Massachusetts, Minnesota, New York, North Carolina, Oklahoma, Tennessee, Vermont, and Wisconsin).

[1] Externally, adult A. oinophylla are visually indistinguishable from Aspilanta ampelopsifoliella – the two species can only be differentiated by examination of the genitalia.

[1][2] The leaf mine begins as straight or slightly contorted linear mine going towards a leaf vein, usually turning at a right angle and following alongside the vein before turning away from it and expanding into a blotch.

The entire mine typically occupies an area of less than 10 mm2 (0.016 sq in) but may be larger on particularly thin leaves.

When mature and ready to pupate, the larvae cut out a 3.2–4 mm (0.13–0.16 in) long case from their host leaf, leaving an elliptic hole.
