Description Edit

It is between 39–57 mm (1.5–2.2 in). The male has a metallic blue-green body and black wings. The female is duller brown with smoky wings that have white spots near the tips (pseudopterostigmata). The naiad is pale brown with darker markings.[2]

Habitat Edit

It lives near wooded streams and rivers, but it can move far from water.[3]

Breeding Edit

Ebony jewelwings mate in the summer. The male holds the female behind her head with his tail or abdomen. The female lays eggs in the soft stems of aquatic plants. The naiad eats small aquatic insects. When the naiad is fully grown, it crawls out of the water and molts.[4]

Flight season Edit

This damselfly species can be seen almost year-round in some regions.[5]
