It is a medium-sized dragonfly with a wingspan of 60-85mm. Adults are greyish to greenish yellow with black and pale markings and green eyes. Its abdomen is greenish-yellow, marked with black. It is very similar to
Orthetrum serapia in appearance, with both species appearing in northern
Australia. Pale markings on segment four of the abdomen do not extend into the posterior section when viewed from above on
Orthetrum sabina. Females are similar to males in shape, colour and size; differing only in sexual characteristics. This dragonfly perches motionless on shrubs and dry twigs for long periods. It preys voraciously on smaller butterflies and dragonflies. ==Gallery==
