 It is only in the last 20 years that odonaterists have been separating "C. parvidens" from "C. viridis" so some of the older records for "C. viridis" will probably be for "C. parvidens".In the field it is not possible to reliably distinguish "C. viridis" from "C. parvidens".Both species are mainly metallic green, like the "Lestes" damselflies, but larger and darker but they do not have a powder blue pruinescence which is common in Lestes.
