AppearanceMature males are olivaceous with a broad stripe in the wings extending between the nodus and pterostigma. Males become pruinose, but the cerci remain pale. The wing band becomes progressively darker with age. Females may be similar to the male, but with a paler, reduced stripe in each wing that does not reach the pterostigma. Other, generally more common, females lack a prominent wing band, but have dark wingtips. Young individuals of both sexes have pale rectangular spots laterally on the abdomen. Occasionally the hindwing may be amber or brown basally.
Total length: 38-47 mm; abdomen: 23-34 mm; hindwing: 25-34 mm.
