Size66 to 70 mm wingspan
WhenMay to August

The southern skimmer is a medium sized dragonfly with a body around 40 to 45 mm long. Mature males develop a pale blue, powdery bloom over the thorax and abdomen and a whitish blue face, while females and immature males stay yellowish to greyish brown with a dark mid-line down a flattened abdomen; the clear wings carry a pale brown to yellow wing spot.

It breeds in small, sun warmed streams, canals, and irrigation ditches with shallow water, where adults perch on bare ground or low stones at the water's edge and dart out to catch mosquitoes, flies, and other small insects.
