Dielis plumipes

Females of D. plumipes have a black scutellum and yellow bands on the first three or four tergites.[2] The setae along the pronotal collar are usually orangish.[1] Males, as in most species of the genus, have yellow bands on the first four tergites and primarily whitish setae on the body.[3] They have the pronotum entirely black, or nearly so, and are distinguished chromatically from allied species by the entirely black clypeus and by the entirely black mid and hind legs.[2]

D. plumipes occurs in the eastern and central United States.[4] The largest populations are the central subspecies, D. p. confluenta, and the southeastern subspecies, D. p. fossulana. A third subspecies, the nominate D. p. plumipes, occurs in a small pocket along the eastern coast within the Carolinian life zone.[2]

There are three subspecies of D. plumipes:[5]

• Dielis plumipes confluenta (Say, 1823)
