The orange-spotted emerald, Oxygastra curtisii, is a dragonfly in the family Idomacromiidae. It is the only species of the genus Oxygastra. The species is native to western and southern Europe, where it inhabits slow-flowing rivers and streams with well-vegetated banks. It is a bronzy-green dragonfly with bright green eyes and a row of yellow-orange spots along the abdomen.
Orange-spotted emerald is a medium-sized dragonfly, about 53 mm in length. It has bright green eyes and a bronzy-green body with a series of yellow to orange spots along the upper surface of the abdomen, giving rise to its common name. The tenth abdominal segment of the male is prolonged into a downward-curving point, a characteristic noted by Selys when he established the genus Oxygastra in 1871.
The wings are transparent, although females often have a pale amber wash at their bases. The sexes differ in the shape of the terminal abdominal segments, with females having a shorter abdomen and a small vulvar scale used during egg-laying.

GBIF citizen-science records
It is estimated from how often the Orange-Spotted Emerald is recorded against all the insects logged in Cévennes National Park (21 verified sightings from 2019 to 2026), calibrated against known sighting rates. Figures are rounded to the nearest 10% because citizen-science data supports honest approximations, not decimals, and months with records from fewer than five people show "—". How it works.
