I was standing on a chair holding the camera over my head, trying to position it so the autofocus and flash were aimed right. I took quite a few pictures, but deleted most of them because they were really bad. These are actually the best.

Hey there Chuck,
I have been reviewing some mosquitoes on Bugguide, and I have an idea for your specimen. Check out this page and tell me what you think about Orthopodomyia: http://www.mosquito-va.org/signifera.htm. The only Orthopodomyia in your area would be signifera and the light lines on the thorax seem a close match. I was thrown off initially because in the dorsal shot seems to show a pointed abdomen, but of course in the other shot the abdomen looks more rounded. Anyway, let me know what you think. I will show your picture to Dr. Darsie tommorow and see what he thinks. If he confirms this than we can make a page and add another genus of mosquitoes to Bugguide.
Oh, yeah, the range info on the website I gave you is incorrect. Darsie and Ward (1) have the range right into coastal S. California.

Just wondering. It kind of looks like Aedes aegypti, but seems to have a white stripe on the proboscis, reminding me of Aedes taeniorhynchus. The best way to ID these guys is specimen in hand, with a scope and a key. Good shot nonetheless. I appreciate the difficulty in photographing these.
