Archaeophya adamsi, commonly known as Adam's emerald dragonfly or horned urfly, is a species of dragonfly belonging to the family Gomphomacromiidae.[2] This is an Australian endemic and one of the rarest dragonflies in the country. It breeds in rivers and streams in coastal areas of Queensland and New South Wales.[3]

Nymphs of this species grow to 23 mm in length and live among rocks and detritus along stream margins. They can be identified by the distinctive two-lobed frontal plate on the head. The nymph lives for around 7 years. The adult is a fairly large and robust dragonfly, blackish brown with narrow yellow rings. The adult probably only lives for a few months.



There is uncertainty about which family Archaeophya adamsi best belongs to: Gomphomacromiidae,[2] Synthemistidae,[4] or Corduliidae.[5]
