Description

Aeshna speciosa fossil

These are relatively larger dragonflies. Their thorax and abdomen have a brown color, with blue or yellow stripes or spots on the thorax, and yellow, blue or green spots on the abdomen.

Natalia von Ellenrieder's 2003 paper demonstrated that the Holarctic and Neotropical species placed in this genus did not share a common ancestor, and proposed the latter be placed in the genus Rhionaeschna.

The spelling 'Aeschna' has been intermittently used over a period of time, but is now abandoned for the original name 'Aeshna'. However, derived genus names (such as Rhionaeschna) retain the 'sch' spelling, as this is how they were first cited.
