Day-flying moth - Diastictis fracturalis

Day-flying moth - Diastictis fracturalis
Santiago Oaks Regional Park, Orange, Orange County, California, USA
May 7, 2010

Moved from ID Request.

Probably safe to say Diastictis fracturalis
Of the nine species in NA, four are recorded from CA; D. caecalis and D. ventralis have minimal to no white forewing maculation so we can rule those out immediately, and D. sperryorum has slightly different FW markings ("the spot in the distal part of the cell always seperate from the one below the cell" according to Powell and Opler; in your image these markings appear to be connected). This leaves us with Diastictis fracturalis, a somewhat variable but widespread southwestern species. I believe this is also the first CA record for this moth on bugguide.

Thanks, all. I do believe that nails it.
And yes, Chris, it's a California first. (I log US and state firsts now, but got started late in doing it.)

Nice find, Ron
...and it took him just over three months to make it to Santa Clara in the bay area from where he was in Southern California when you got your shot of him!

Hey, Mac, I give 'em a flight plan, but no schedule.
Glad you got a shot at him!
