The red-veined darter or nomad (Sympetrum fonscolombii) is a dragonfly in the genus Sympetrum. There is genetic and behavioural evidence that S. fonscolombii is not closely related to the other members of the genus Sympetrum and it will at some time in the future be removed from this genus.
Sympetrum fonscolombii was named under the protonym Libellula fonscolombii by the Belgian entomologist Edmond de Sélys Longchamps in 1840, in honour of the French entomologist Étienne de Fonscolombe, whence the species name. Its name is sometimes cited as fonscolombei instead of fonscolombii, but Askew (2004) gives the latter as the correct spelling.
Sympetrum fonscolombii is a widespread and common species in much of central and southern Europe including most Mediterranean islands, North Africa, the Middle East, Mongolia, south-western Asia, including the Indian subcontinent, the Indian Ocean Islands and Sri Lanka. In Europe it is resident in the south of its range but in some years it migrates northward. From the 1990s onwards, it has increasingly been found in northwest Europe, including Belgium, Sweden, Finland, Poland, Great Britain, and Ireland... Wikipedia →

With luck
About 10% of wildlife watchers report a Nomad sighting in Sierra Nevada National Park on a given day, based on 5 verified sightings from GBIF citizen-science data from 2019 to 2026. It is the 390th most-seen of the 479 insects we can rate there. Over three days the chance rises to about 20%, and over a week to about 50%, if each day is a fresh chance.
May–July and September–October
In those months about 10% of wildlife watchers report a Nomad in Sierra Nevada National Park on a given day, against under 5% in August and November–April, the lowest months.
Between 11 am and 2 pm
Across all the parks we cover, that three-hour window holds the most Nomad sightings with a recorded time, and about 9 in 10 of them come between 6 am and 6 pm: it is a daytime animal.
10th of 14
Of the 14 parks where we can rate Nomad sightings, Sierra Nevada National Park ranks 10th at about 10%. The best odds are in Doñana National Park (Spain, about 40%), Camargue (France, about 30%) and Mercantour National Park (France, about 20%).
Same genus: Sympetrum
The closest relatives of the Nomad that you can see in Sierra Nevada National Park (genus Sympetrum, Meadowhawks) are Desert Darter (about 10%) and Common Darter (about 10%), with each one's daily chance of a sighting.
GBIF citizen-science records
It is estimated from how often the Nomad is recorded against all the insects logged in Sierra Nevada National Park (5 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.
