Swarming Epicauta on mesquite  - Epicauta pardalis

Swarming Epicauta on mesquite - Epicauta pardalis
Sierra Vista, Cochise County, Arizona, USA
June 26, 2010
Maybe E. pardalis? These beetles were at amazing densities on mesquite trees, they seemed to be moving from tree to tree in a swarm.

Moved
Moved from Epicauta.

thanks for the confirmation!

Epicauta pardalis
commonly swarms on mesquite and may defoliate individual trees. This month (unusually) a very similar species, E. andersoni is very common at the base of the Chiricahua Mtns. on Chaenopodium and Salsola, with E. pardalis on the mesquites in the same area.

 
Do you know which one would be on this plant
in western New Mexico?
