Geometrid Moth - Stenoporpia pulchella - Male
Valley Station, Palm Springs Aerial Tramwa, Riverside County, California, USA
April 1, 2008
Color is off here, but the wall was tan, so I'm not sure how much it's off. The moth was a yellow tan with brown markings.

Moved - Tentative
Moved from Ennominae.

Pectinate antennae = ♂
Lynette, have a look at the info tab. The other two, closely related species may not range into California, but I'm not sure of that.

Moved from Geometrid Moths.

Stenoporpia pulchella?
This is not an identification, at least not yet anyway, but I'm wondering if this might possibly be Stenoporpia pulchella? It compares relatively favorably with the BOLD photographs, and it has been recorded from Riverside County. The flight records MPG has are February, March (this photo is from April 1st which is close enough to the known flight records, I'd think), September, and November. Looking through MPG at related species, it seems that there a limited number of yellowish-gray ones compared with the number of cool gray ones. I didn't find a better match on MPG, but I'd be interested to hear other opinions on the moth.

Stenoporpia pulchella
Thanks Josiah. It certainly looks possible to my untrained eye. Here is the link to MPG quick access for anyone else that wants to weigh in.

Thanks for putting in the li
Thanks for putting in the link, I might as well include the BOLD link as well, here it is. As a side note, I also notice that your moth has feathery (I believe it would be technically called pectinate) antenna, which also matches Stenoporpia pulchella.
