The Epaulet Skimmer is a southern European and African dragonfly. A little similar to the Keeled Skimmer of the UK, it has a narrow elongated body with central raised "keel". Above is the attractive pale blue male with turquoise eyes, but the "epaulet" marking on the thorax that gives it its name is not often clear and darkens with age.
The Epaulet Skimmer frequents a wide range of freshwater habitats, including Rivers, streams, lakes, pans, dams, and water-holes. It prefers sites that are fairly open with exposed rocks, sand, or gravel. The Epaulet Skimmer is most numerous along rivers in the savanna regions.
The Epaulet Skimmer often perches on the ground, but also on rocks and exposed stems and twigs. It hunts from a perch with a rapid, darting flight. Frequently returns to the same perch. Both sexes can be found in the same vicinity.
The Epaulet Skimmer is common and widespread in South Africa. It is listed as of Least Concern in the IUCN Red List of Threatened Species. The Epaulet Skimmer is fairly resistant to habitat damage and is often common at man-made and degraded sites.
