Potato Beetle Larva

Dear Zombiemarble,
This is a Leaf Beetle Larva in the family Chrysomelidae, and larvae can often be quite difficult to properly identify.  Knowing the food plant is often a tremendous assistance.  There is a strong resemblance to the larva of the Colorado Potato Beetle (see BugGuide), however, this is not a Colorado Potato Beetle larva.  We suspect it is another member of the genus, or perhaps a closely related genus.  Though BugGuide does not picture the larva, circumstantial evidence leads us to speculate that this might be the larva of the Reddish Potato Beetle,
Leptinotarsa rubiginosa, a species only reported from Arizona on BugGuide.
