Identification
Augochloropsis anonyma is virtually indistinguishable from other members of the tribe Augochlorini (Augochlora, Augochlorella, and Augochloropsis) without microscopic examination. All three in this tribe are bright metallic green or -green. To distinguish Augochloropsis from (), observe that sweat are usually found on flowers, and alight more directly, and move less swiftly than the quick, jerky movements of cuckoo wasps. Female sweat bees collect pollen using (brushes of hairs) on the hind legs, which cuckoo wasps lack.
