Chalcolestes parvidens, formerly Lestes parvidens, is a damselfly of the family Lestidae. It has a metallic green body and at rest it holds its wings away from its body. Its common name in (American) English is the Eastern Willow Spreadwing.
The genus Chalcolestes is separated from Lestes because of differences in their larvae. C. parvidens is closely related to C. viridis and used to be considered a subspecies of C. viridis, however there are small morphological differences between the two species both as adults and larvae and analysis of proteins from the two species, by electrophoresis, also supports their separation into two species, but they are hard to tell apart in the field.
C. parvidens is found in eastern and central Europe, in Croatia, Bulgaria, Greece, Italy, Syria, Jordan, Israel and Turkey. It is found on islands in the eastern Mediterranean; on Cyprus, Corsica, Crete and Sicily. In Italy and the Balkans both C. parvidens and C. viridis occur together. 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.
