Flea beetle? - Altica

Flea beetle? - Altica
Organ Mountains foothills, Doña Ana County, New Mexico, USA
August 6, 2006
This is a lamentable case where I neither measured nor photographed the underside of this beetle. Because of the last, I'm not even sure it's a flea beetle. With what I can see of its femurs from the dorsal view I could go either way. Regarding the former oversight, my guess is that it is somewhere in the 3.5 - 4 mm range. If it were much larger, it would have stuck me as unusually large. If it were much smaller, I could not have gotten the detail I did with my lens.

yes a fleabeetle. The antenna are situated in between the eyes. This means in galerucinae....thus alticini. The femurs are pretty clearly swollen as well.
Maybe Altica...

 
Thanks, Rob.
I've stuck on the tribe page.
