The common baskettail (Epitheca cynosura) is a species of dragonfly in the family Corduliidae.

The scientific name, cynosura, means dog tail, and possibly refers to way the cerci at the end of the abdomen curve outward like a dog wagging its tail one way then the other.

Some specimens have a triangular spot at the base of the hindwing.

The caudal appendages (structures at the tip of the abdomen) differ between the species and can be compared with known drawings or close-up photos.
