Desmia maculalis -  Canyon Creek, Clark County, Washington, USA June 6, 2023 Size: Forewing length 11mm
I believe this is Desmia maculalis based on the striped ventral abdomen. This was found at least 10 miles from any human habitation, so my guess is that it’s larval host must have been one of the Oenothera (evening primrose) since none of the other known hosts are found anywhere near there.
