Facilitating the protection and restoration of endangered species and ecological communities on BC’s South Coast

COSEWIC: Not listed, BC List: Blue

Length: males: 4.1—4.6 cm, females: 4.0—4.3 cm. Males are slightly larger, sexes are highly dimorphic in colouration. Adult males have dark blue-green eyes, immature and adult females have light green to olive eyes. The face of both sexes is light green. Eyes just touch at the top of the head with a small triangular patch of brown hairs between. Mature males have a distinct “pruinescent” (dusty or frosty looking), thorax and abdomen (lacking in immature males and females). Top leading edge of both sets of wing membranes in mature males is lined with black from wing base to the pterostigma (coloured, thickened cell on the leading edge of each wing membrane near the tip). The pterostigma of both sexes is narrow and light brown. Immature males and all females are yellow-green with a dark line running dorsally the length of the abdominal segments. Lower abdominal segments may be green or yellow-green ringed with brown. The 1.5-1.7 cm larvae are green with distinct diagonal striping on the head. The prominent eyes are located on the sides of the head and turned up. The rounded abdomen lacks abdominal hooks or spines found on the larvae of some other Odonata.
