Toxomerus marginatus? - Toxomerus occidentalis - Female
Aromas, San Benito County, California, USA
August 13, 2007
Size: approx. 1 cm.
I occasionally see these Syrphid flies in our garden, they don't stay still very long. This one looks like it may be Toxomerus marginatus, based on other photos on this site.

Oh, I'd say it's a bit more special than that.
T. marginatus is quite common. Yours, I'm convinced, is T. occidentalis, a west coast version of T. geminatus.


Hopefully, you'll get an expert confirmation on this. (If not, check out Martin Hauser's visual key somewhere in the Toxomerus section and make your own diagnosis.)

Thanks Ron
I've looked at the key http://bugguide.net/node/view/72726, and I think you are right. Thanks for the ID help.

Moving
If you move it yourself you are saving the overworked editors some extra time. Tag it, go to the right page and click on move tagged image.

Thanks Beatriz
I've only been posting to this site for less than a month, wasn't sure if I should move my own images or not. I've moved this and a few of my other images.

Times change
When I started there was no need to ask all the contributors to help when they could. There were very few entries those days, but now with over 250 submissions a day and perhaps 90 of them to ID request, we need all the help that we can get. Thanks for your contributions and thanks for helping.

Yes, it must be occidentalis if it in the West. I would go ahead and move it.
