Webb Canyon, ~2000 ft. altitude, Los Angeles County, California, USA
April 5, 2009
Size: ~4 mm
Another pool rescue with a happy ending -- this one seemed none the worse for wear and flew off after its wings dried out a bit. After looking through my possible beetle options, I think this one looks most like one of the the Casebearers (Subfamily Cryptocephalinae) -- perhaps one of the members of Genus Cryptocephalus
? I believe this group is characterized by the base of the pronotum being as wide as the elytra... Of the species listed in the guide, I couldn't find any patterns that matched up with mine, but The California Beetle Database
lists 12 species in this genus and BugGuide currently only has images for 2 of those species.
I have MANY more photos of this specimen which I may post later, but I simply couldn't wait to find out more about this little one! Anxiously waiting to hear whether my guesses are right and if it is possible to obtain a species ID...
Specimen photographed in the shade -- much shinier and red more vivid in the sunlight. Mixed oak & chaparral habitat.
