The vagrant darter, or moustached darter, (Sympetrum vulgatum) is a European dragonfly. The species takes its English name from its habit of occasionally appearing as a rare vagrant north of its normal range. However, it is likely to be under-recorded because it is very similar to the common darter (S. striolatum).
The species is common in central and northeast Europe. It breeds in standing water. Wikipedia →

Rare
Under 5% of wildlife watchers report a Vagrant Darter sighting in Wadden Sea National Park on a given day, based on 14 verified sightings from GBIF citizen-science data from 2019 to 2026. It is the 361st most-seen of the 818 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.

GBIF citizen-science records
It is estimated from how often the Vagrant Darter is recorded against all the insects logged in Wadden Sea National Park (14 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.
