13-6-2016 VILLALONGA RESERVOIR - EPAULET SKIMMER DRAGONFLY (Orthetrum chrysostigma)

Both sexes are among the more easily recognised Orthetrum species, due to the single diagonal stripe on the sides of the thorax.

Fully pruinose males, however, are hard to identify and are best told by the distinctive shape of the secondary genitalia.

Most similar to the closely related Two-striped Skimmer (Orthetrum caffrum), but that species has a darker, browner thorax with two, pale diagonal stripes on the sides.

Makes use of a wide range of freshwater habitats, including Rivers, streams, lakes, pans, dams and water-holes. Favours sites that are fairly open with exposed rocks, sand or gravel. Most common along rivers in the savanna regions.

Often perches on the ground, but also on rocks and exposed stems and twigs. Hunts from a perch with a rapid, darting flight. Frequently returns to the same perch. Both sexes can be found in the same area.

Common and widespread. Listed as of Least Concern in the IUCN Red List of Threatened Species. The Epaulet Skimmer is fairly resistant towards habitat damage and is often common at man-made and degraded sites.

Very widespread and occurs virtually throughout Africa, including North Africa. It also occurs in parts of Southern Europe and the Middle East. In South Africa it occurs virtually throughout, but is scarce in the dry central regions.
