Sympecma fusca, the common winter damselfly, is a damselfly a member of the Lestidae and related to the emeralds or spreadwings. This species can be found in much of southern and central Europe stretching out to Asia where it is replaced by S. paedisca. It is found around the Mediterranean in Europe and North Africa and on many Mediterranean islands.
It can be found in all types of standing water, including in brackish waters. In winter adults are found away from water on dry plant stems usually in open areas such as grassland and heaths. Sympecma fusca can reach a length of about 38 millimetres (1.5 in). It is distinct from all other European damselflies except Sympecma paedisca, so in most of its range there are no problems with identification. It does not have the bright blue or red colouration that is more usual for damselflies so it is often overlooked. It does not have the metallic emerald green sheen... Wikipedia →

With luck
About 10% of wildlife watchers report a Common Winter Damselfly sighting in Stockholm on a given day, based on 9 verified sightings from GBIF citizen-science data. It is the 123rd most-seen of the 202 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.
March, May and August–September
In those months about 10% of wildlife watchers report a Common Winter Damselfly in Stockholm on a given day, against under 5% in April, June–July and October–February, the lowest months.
Between 1 and 4 pm
Across all the parks we cover, that three-hour window holds the most Common Winter Damselfly sightings with a recorded time, and about 9 in 10 of them come between 6 am and 6 pm: it is a daytime animal.
Among the best
Of the 16 cities where we can rate Common Winter Damselfly sightings, Stockholm ranks 11th at about 10%, level with the leaders once rounded. The best odds are in Budapest (Hungary, about 10%), Vienna (Austria, about 10%) and Lyon (France, about 10%).
Same order: Odonata
The closest relatives of the Common Winter Damselfly that you can see in Stockholm (order Odonata, Dragonflies and Damselflies) are Vagrant Darter (about 10%), Common Blue Damselfly (about 10%) and Four-Spotted Skimmer (about 10%), with each one's daily chance of a sighting.
GBIF citizen-science records
It is estimated from how often the Common Winter Damselfly is recorded against all the insects logged in Stockholm (9 verified sightings), 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.
