Length: 5-7 mm
Zygogramma suturalis is often found on Ragweed in rich, moist habitats. In the fall it may be seen visiting Goldenrod flowers.
The dark areas often have a bronze luster, or occasionally greenish. The elytral punctures are in distinct rows, though towards the edges they are less regular. The last section of each tarsus has a distinct tooth on its ventral side (Downie and Arnett, 1996).
The adults of this species are found most commonly in the Mountain State in June, July, and August.
