Green-headed coneflower, mine #1 - Dichomeris washingtoniella

100 Acre Wood, Winneshiek County, Iowa, USA
August 26, 2019

August 26, 2019: collected linear leaf mines, next to mid-vein, on Green-headed coneflower, Rudbeckia laciniata. There appeared to be an emergent hole with each mine but both mines were still occupied by what may be a lep larva.
Both mines, same leaf. This is mine #1
September 10, 2019: as I removed the leaf from the vial to photograph the mines, the larva was emerging from mine #2
September 11, 2019: the larva is back in mine #2
September 20, 2019: larva was mining on new leaf (old leaf was deteriorating)
September 21, 2019: leaf was curled with mine at bottom of curl. Photo of new mine: Right is the mine and Left is external weaving.

Moved from Gnorimoschemini.

At least two of the mining larvae you gave me (these same stripey guys) are still alive, happily feeding on basal leaves of R. hirta or some related cultivar, tying them in a manner much like this:

Oh,

Basal leaves, I've not thought to look, and now its snowing.

Moved

Moved from Unidentified Leaf Mines.

I'm reasonably sure these are gnorimoschemine, but not anything that's been documented before.
