beetle - Cybocephalus californicus
Copyright © 2006 Joyce Gross

beetle - Cybocephalus californicus
Wister Unit, Salton Sea National Wildlife Refuge, Imperial County, California, USA
February 10, 2006
Size: 1mm
Found walking on my shirt. Very tiny with tendancy to roll into a ball. Also was able to jump small distances like a flea (not as big a jump as a flea though).

maybe clambid
Is this a beetle of family clambidae? I'm pretty sure they can roll up, and they have the same general shape as this one. The large coxal plates also point to clambidae.

Coccinellidae?
Possibly another of the very small glabrous coccinellids. It is a member of the Cucujoidea, which does narrow the possibilities, and is not a clambid.

Nitidulidae: Cybocephalus?
Just took a quick look at the Cybocephalus in our collection, and very possibly it is this odd genus. Currently placed in the Nitidulidae, sometimes placed as its own family. If the apices of the elytra are rounded-truncate (can't quite see in the photos), then I would be more sure. I don't think it is a phalacrid - at least I've never seen one like this.

Only .
Looks pretty good, and only one Cybocephalus sp. for certain and another possible listed for California.

Cybocephalus californicus
The word from Trevor Smith is that this beetle is Cybocephalus californicus Horn.

Phalacridae?
I don't know how common they are there, but the Phalacrids come to mind.

Leiodidae.
The round fungus beetles are what come to my own mind, and at least some genera (i.e. Agathidium) are known to roll up, though usually more completely than this. Still, that would be my best guess.
