Moved from ID Request.

Mompha passerella...
...would be the ID here. I have not seen other spp. with which this and M. bottimeri would be confused. And yes, the brownish tinge, if present in the basal white area of the forewing, does seem to occur in M. passerella and not in M. bottimeri. Also, from what little is known about the respective geographic ranges of these two spp., M. bottimeri seems to be restricted to the southern part of the USA.

I am not sure how to rule out Mompha bottimeri
Maybe Terry Harrison would know?

If that is the only other option,
then apparently the brownish tinge is a distinguishing feature, based on his comment here. I just don't know if those are the only two possibilities.

I'm not sure about other options
I looked at BOLD for reference, but there are many species without images there.
