Gomphus vulgatissimus, the common clubtail, is a medium-sized (wingspan 6 –7 cm.) species of dragonfly in the family Gomphidae. It is found in most of Europe, and is present now in the south of France. Its natural habitats are clean, slow moving streaming rivers and creeks with sandy soil. It can be seen from mid-April in the south to August. Once they hatched out of water, they live shortly. As the common name suggests, this medium-sized species has a distinctive club-shaped abdomen. The males are black with extensive yellow markings on the thorax and abdomen which turn green as the insect ages. The females are black with extensive yellow markings. In the British Isles the adult flight period extends from mid May to early July.

GBIF citizen-science records
It is estimated from how often the Common Clubtail is recorded against all the insects logged in Biebrza National Park (11 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.
