Orthetrum

Orthetrum is a large genus of dragonflies in the Libellulidae family.[2] They are commonly referred to as skimmers.

Skimmers
Female Orthetrum chrysostigma
Scientific classification
Kingdom: Animalia
Phylum: Arthropoda
Class: Insecta
Order: Odonata
Infraorder: Anisoptera
Family: Libellulidae
Genus: Orthetrum
Newman, 1833[1]

The size of adults within the genus ranges from small to large; in Africa, the hindwing ranges in length from 22 to 50 mm. The bodies of adult females and recently emerged males are yellow to brown with black markings; these may facilitate identification of individuals to species level. Mature males, however, develop blue-grey pruinosity over most of their bodies - this makes species identification difficult without the capture of a specimen and inspection of the shape of the hamule.[3]
