Exochomus in California #1 - Exochomus fasciatus

Webb Canyon, ~2000 ft. altitude, Los Angeles County, California, USA
March 16, 2009
Size: ~2 - 3 mm

Another pool rescue... (please ignore the little bits of white stuff on the beetle -- some sort of detritus from the water). It spent much time trying to dry out its wings and I actually got many more photos with its elytra raised than down. Superficially, this looks like a coccinellid to me, but I couldn't seem to find an exact match in the guide. I'm thinking maybe something in the genus Exochomus? The info page states that there are 10 North American species and there are only 3 currently represented on this site, so I guess it could be one of those others...

I have many more photos, so if there is an important marking or anatomical structure that is needed for an ID, let me know what it is and I will try to find an image. Thanks!

Mixed oak and chaparral habitat.

Yes! Exochomus fasciatus

This is E. fasciatus Casey 1899. Gordon states this one is confined to the LA area of SoCal! Individuals may entirely lack dark band at middle, or appear as yours does. Highly polished.

If you have additional dorsal images, suggest adding one or 2 more.

Great find! And another new species for BugGuide :)

Dorsal shot...

Tim, I'm still looking through my images, and so far I'm not sure I have anything spectacular to add. However, I just posted an image of a specimen I found yesterday to ID request (here). If it is the same species, then we could add that one.

Just the man I was hoping to hear from!

Thanks, Tim. For the exciting ID news and for creating the new species page. As I said in my post, this little guy gave me way more shots with its wings up then down, but I will go back through my images and see what I can dig up. I have a vague memory that maybe I had another similar specimen in my photo files too... will definitely go and have a look. Again, thanks so much!
