    Orthetrum: Brief Summary
    provided by wikipedia

    Orthetrum is a genus of dragonflies in the Libellulidae family. It is a very large genus.

    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.
