Mexican Bean Beetle
Thank you! You seem to be correct so I will change the common name on my image. I have been trying to see what is the difference between E. varivestis and E. borealis. In the images that I examined, the only thing that I can see is that E. borealis has black spots on the area directly behind its head whereas E. varivestis does not. I am not sure if that is the distinguishing charectaristic; I am hoping that an expert can be more specific.

good book
I'm not an expert, but I do have a hard to find copy of an expert's good book.

From the key to species of
Epilachna, E. varivestis
= "each elytron with 8 dark spots; pronotum immaculate" (spotless), while
E. borealis
(and one other species found only from western TX and southern AZ) = "each elytron with 7 dark spots; pronotum usually with 4 dark spots".
As yours doesn't have any spots on the pronotum, it would seem to be
E. varivestis
:)
