Adela trigrapha ? - Adela trigrapha - female

Adela trigrapha ? - Adela trigrapha - Female
Willow Springs, San Benito County, California, USA
April 8, 2012
Size: ~8mm length.
I was photographing the flower this guy is sitting on when I noticed him, so I zoomed in to get a closer shot, got only one before he left. He's pretty distinctive, I assume it is Adela trigrapha. 36.66814°N, 121.03120°W.

Moved from Adela. Unfortunately the orange head is not the only character for A. eldorata, females of A. trigrapha can also be orange (and occasionally a male). But given that this is a coast range moth and has narrower bands I'll stick with trigrapha. Gary do you recall the antennae being "short" for an Adela?

This is a female, independent of antenna length
Chris, I'm assuming you asked about antenna length to help ascertain whether this is a male or female here (as I believe antenna length doesn't clearly separate male [nor female, respectively] eldorada and trigrapha.)

But the eye size, when clearly discernible as it is here, is perhaps a better character for separating male and female in these two species...since the males have nearly holoptic eyes, with the eye diameter being 3× or more the distance between the eyes, whereas the females have much smaller eyes (about 2/3 distance between eyes at top of head). Thus, this is clearly a female.

If this had been a male...then in light of couplet 7 in Powell(1)...the abundant orange scales on the crown would have been persuasive of eldorada over trigrapha here, though the elevation and range would still be incongruous with previous records (which is always the nature of range extensions).

I don't remember
the antennae, but there is a photo of another specimen from the same area, taken a couple of weeks later. .

Moved from ID Request.

Outside my fauna and too close to #0226 for me to call.
