Looks similar to some members of Trirhabda. In Xanthogaleruca antennomere 3 is longer than (or subequal to) antennomere 4, shorter in Trirhabda(4)
At the base of each elytron in the typical form of X. luteola there is a short, dark, medial spot or stripe(4) (may be obscured in forms with uniformly dark elytra)

In addition to the occipital spot present in both genera, X. luteola usually has a second "frontal" spot on the head just above the antennae, rarely present in Trirhabda
X. luteola is usually found near parks or towns where elm trees have been planted. Trirhabda spp. are native and usually occur in less disturbed areas.
