Explanation of Names
Calligrapha suturella Schaeffer 1933
suturella refers to the spot-pattern along the elytral suture
Size
8.0–9.2 mm (1)
Identification
Specimens like this, coming from NE North America can be found in many collections mingled with Calligrapha multipunctata, for they share the pale margins of pronotum and the lack of a diagnostic spot laterally on elytra. However, it is a different species: Calligrapha suturella Schaeffer, which we have postulated to be parthenogenetic. The most remarkable difference between both species (although not constant)is the fusion of sutural and subsutural longitudinal dark stripes on elytra (i.e., the stripes running along the junction of both elytra).

Range
ne. NA to NY-MN-MB (2)
Food
Willows - Salix spp. (Salicaceae) (1)

C. multipunctata bigsbyana, C. suturella, and C. philadelphica are similar, but differ in pale pronotal band and elytral markings (1)
