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.

Rare
Under 5% of wildlife watchers report a Common Clubtail sighting in Cévennes National Park on a given day, based on 6 verified sightings from GBIF citizen-science data from 2019 to 2026. It is the 814th most-seen of the 996 insects we can rate there. Over three days the chance rises to about 10%, and over a week to about 30%, if each day is a fresh chance.
June
In that month about 10% of wildlife watchers report a Common Clubtail in Cévennes National Park on a given day, against under 5% in July to May, the lowest months.
Between 9 am and noon
Across all the parks we cover, that three-hour window holds the most Common Clubtail sightings with a recorded time, and nearly all of them come between 6 am and 6 pm: it is a daytime animal.
4th of 5
Of the 5 parks where we can rate Common Clubtail sightings, Cévennes National Park ranks 4th at under 5%. The best odds are in Plitvice Lakes National Park (Croatia, about 40%), Biebrza National Park (Poland, about 30%) and Białowieża National Park (Poland, about 20%).
GBIF citizen-science records
It is estimated from how often the Common Clubtail is recorded against all the insects logged in Cévennes National Park (6 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.
