With luck
About 10% of wildlife watchers report a Black-Tailed Skimmer sighting in Cévennes National Park on a given day, based on 20 verified sightings from GBIF citizen-science data from 2019 to 2026. It is the 555th most-seen of the 996 insects we can rate there. Over three days the chance rises to about 20%, and over a week to about 40%, if each day is a fresh chance.

Across all the parks we cover, that three-hour window holds the most Black-Tailed Skimmer sightings with a recorded time, and about 9 in 10 of them come between 6 am and 6 pm: it is a daytime animal.

GBIF citizen-science records
It is estimated from how often the Black-Tailed Skimmer is recorded against all the insects logged in Cévennes National Park (20 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.
