The Lestidae are a rather small family of cosmopolitan, large-sized, slender damselflies, known commonly as the spreadwings or spread-winged damselflies.
Wingspan: 3 – 7.5 cm
The two subfamilies in Lestidae are Lestinae and Sympecmatinae. Damselflies in the Lestinae rest with their wings partly open, while those in the Sympecmatinae, the reedlings, ringtails, and winter damselflies, rest with their wings folded. The exact taxonomy of the family is disputed, with some authorities including twelve genera and some eight.
