Lestes dorothea,[2][1] the forest spreadwing, is a damselfly species in the family Lestidae.

The dorsum of the thorax is marked with a pair of metallic green antehumeral stripes shaped like those seen in L. praemorsus.

Anal appendages are bluish during life, broadly black at base and apex.

[4] Female thorax is olivaceous green, pale greenish yellow laterally.

[4] Its much larger size, the absence of markings on segments 8 and 9 in the male, diffuse black stripes on the humeral suture, and higher postnodal index will serve to distinguish it from L.
