This beautiful lime green beetle with purple legs (imagine this being real!) It is a Beyer's Leaf Chafer Beetle (Chrysina beyeri), which feeds on oaks in the mountains of Southeast Arizona. This one was photographed in Madera Canyon, Arizona, and was apparently "chafing" the leaves here, whatever that means :-)
This common butterfly gets overlooked at times, but is very beautiful if you look closely at its colors and markings.
