description Bleached Skimmer Overview

The Bleached Skimmer (Libellula composita) is a dragonfly species in the family Libellulidae native to western North America. Mature males develop a distinctive chalky white pruinosity—a waxy coating—across the abdomen, giving the insect its common name. This species inhabits desert and arid regions, where the pale abdominal coating may assist with reflecting sunlight and regulating body temperature in hot environments. It can be found near ponds, streams, and other shallow waters across the southwestern United States.

help Bleached Skimmer FAQ

How can I identify a male Bleached Skimmer?

A mature male Libellula composita develops a chalky white wax coating, called pruinosity, over much of its abdomen. Its dark thorax and dark markings near the bases and tips of the wings help distinguish it from other pale skimmers.

Do female Bleached Skimmers turn white too?

Females and immature males generally retain a darker brown or patterned appearance instead of the adult male's strongly bleached abdomen. This difference can make the sexes look surprisingly unlike each other in the field.

Where should I look for Libellula composita?

The species occurs in western North America and is usually found near still or slow-moving freshwater. Ponds, marshes, sluggish streams, and irrigation channels with open perches are typical places to search.

Is the white coating on a Bleached Skimmer a disease or dust?

No. It is a normal waxy bloom called pruinosity that develops as the male matures, much as it does in several other dragonflies.
