Observation notes: Near a floodlight on my deck. The hindwing doesn't seem right for any of the options.

Coordinator notes: I just read the comments on Bugguide for your moth --
Macaria amboflava - vs. - Macaria sulphurea
"However, more current data than Ferguson (2008) does have sulphurea collected in the pacific northwest and there is a growing number of sequenced male individuals from that population that are quite yellow, and quite well marked. As more individuals of the two species are sequenced, we're finding that the external characteristics are less reliable than previously thought--or so it seems based on the genetic evidence. So distinguishing yellow individuals by photo in overlapping distribution locales may prove difficult or impossible at this time."
