LepiLED light trap. Tentative ID but seems like a good match for this one (and none of the other Agonopteryx known from Canada):

Kyle Johnson collected a specimen from Mackinac Co (MI) in a similar habitat on Sept. 18, 2018.
"sand dune ridges/wetland swales with scattered Larix-Pinus-Thuja-Picea-Betula woodland groves."

[Sept 9, 2021 edit: Kyle Johnson commented:
'sure looks like it to me. Agonopterix lythrella is similar size and pattern (and flies around the same time), but with a distinct dark reddish cast.
Wow, surprising that is new to Canada, given collection efforts on Manitoulin Island and other places. Shows how much we don't know! I've taken it in a few other northern Michigan locations as well, in addition to Mackinac. Co. Should be sought elsewhere in Ontario, esp. near the border with Michigan.

Gelechiidae. Photographed at Hudgin-Rose Property, Prince Edward County, Ontario on 21 July 2019. Small (TL about 5-6mm) and with a rather distinctive FW pattern and largely white head. However, in spite of trying quite hard I cannot place this one...
Gelechiidae. Photographed in Toronto, Ontario on 30 July 2018. Rather small with a TL of about 5-6mm. Conspicuously patterned, but I cannot find a match for it yet...
On e-Butterfly: EB-C43954/EB-169197.
At light. Known to breed in nearby calcareous fen.
If ID is correct, and it seems pretty certain, this would be a first record for Canada. It is not shown on either MPG, BugGuide or iNat as occurring in Canada, although it does occur in Ohio.
First Canadian record of family/species, Epipyropidae/Fulgoraecia exigua.
Found Acanalonia conica with white growth on side of abdomen. I thought it was a fungus but it is actually a fuzzy looking caterpillar/larva, feeding on the planthopper.
dozens of individuals swarming, flying around and staying close to Sorghastrum nutans.
