Willow calligrapha

Calligrapha multipunctata and Calligrapha philadelphica are easily confused with each other. The clearest difference is that Calligrapha multipunctata has considerable white on the pronotum. Calligrapha philadelphica has an all-dark pronotum.

Food plants will also distinguish the two species. Calligrapha multipunctata feeds on members of the Willow family, while Calligrapha philadelphica feed on Silky Dogwood and other Dogwoods.
