It inhabits a wide range of still and sluggish waters, often shallow. In Australia it ranges from the top end of the Northern Territory to about Mackay in central Queensland.

Description

Orthetrum serapia is a medium-sized dragonfly with a wingspan of 60-85mm. Its wings are clear except for a small dark spot at the base of the hindwing. The thorax is greenish to greyish yellow with black markings. The abdomen is black with pale yellow or pale green markings. Orthetrum serapia appears very similar to Orthetrum sabina and can be confused where the range of the two overlaps in north-eastern Australia.
