Explanation of Names
According to Zeller, from Greek chalkos (χαλκος) + helas (ηλας)- "nail", due to the marking on the hindwing (? German "Hinterflügelzeichnung") (that would be of the type species, Chalcoela aurifera, since it was the only one known at the time).

moths are parasitoids
of paper wasps, Polistes
species. Larvae feed on the larvae and pupa of the wasps. The caterpillars spin a characteristic web in the cells of the wasp nest. There are several generations per year, and the caterpillars (or pupa?) overwinter in the wasp nest (Hughes 2002).
