Calligrapha multipunctata 'bigsbyana' form -det. J.Gómez-Zurita
his comment: "very common in that part of the US. It is interesting that they were found in numbers on cottonwood (poplar?) leaves, since they are nearly always associated with another Salicaceae: several species of willow across North America."

Moved from subgenus Calligrapha.

Calligrapha maybe?
Looks like something in the Calligrapha genus, in the Chrysomelidae.
