In 3 days ~40% in a week ~70%
The white-faced darter or small whiteface (Leucorrhinia dubia) is a dragonfly belonging to the genus Leucorrhinia in the family Libellulidae, characterised by red and black markings and a distinctive white patch on the head. It is found in wetlands and peat bogs from northern Europe eastwards to Siberia, and the adults are active from around April till September, which is known as the "flight period". It breeds in acidic bodies of water, laying its eggs in clumps of sphagnum moss that provide a safe habitat for larval development. The larvae are particularly vulnerable to predation by fish, and so are usually found in lakes where fish are not present. L. dubia is listed as a species of least concern (LC) by the IUCN Red List, however, it is potentially threatened by habitat destruction, pollution, and climate change.
This species has a predominantly black body, usually 33–37 mm (1.3–1.5 in) in length - the abdomen is 21–27 mm (0.83–1.06 in) long and the hindwing is 23–28 mm (0.91–1.10 in) long. Mature males have striking red and orange markings on the abdomen and thorax which become darker with age, whereas young males and females have pale yellow markings. All individuals... Wikipedia →

Possible
About 20% of wildlife watchers report a Small Whiteface sighting in Vanoise National Park on a given day, based on 18 verified sightings from GBIF citizen-science data from 2019 to 2026. It is the 111th most-seen of the 308 insects we can rate there. Over three days the chance rises to about 40%, and over a week to about 70%, if each day is a fresh chance.
June and July
In those months about 20% of wildlife watchers report a Small Whiteface in Vanoise National Park on a given day, against under 5% in September to May, the lowest months.
Between 11 am and 2 pm
Across all the parks we cover, that three-hour window holds the most Small Whiteface sightings with a recorded time, and nearly all of them come between 6 am and 6 pm: it is a daytime animal.
Yes
Of the 4 parks where we can rate Small Whiteface sightings, Vanoise National Park has the highest daily chance: about 20%. Next come Cairngorms National Park (United Kingdom, about 10%) and Bavarian Forest National Park (Germany, under 5%).
Same family: Libellulidae

GBIF citizen-science records
It is estimated from how often the Small Whiteface is recorded against all the insects logged in Vanoise National Park (18 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.
