Young Chalky Perchers are greenish yellow with black markings on the thorax and abdomen, and males turn increasingly powdery blue with age while many females stay green. The wings are clear, without dark patches at the base or tips.

It breeds in muddy puddles, rice fields and pond edges across a wide range from the Seychelles and Arabian Peninsula to Japan, India and Australia, and often perches low on bare ground some distance from water.
