Rare
Under 5% of wildlife watchers report a Straw Belle sighting in Pyrénées National Park on a given day, based on 10 verified sightings from GBIF citizen-science data from 2019 to 2026. It is the 940th most-seen of the 1277 insects we can rate there. Over three days the chance rises to about 10%, and over a week to about 20%, if each day is a fresh chance.
August and September
In those months about 10% of wildlife watchers report a Straw Belle in Pyrénées National Park on a given day, against under 5% in October to July, the lowest months.
Between 5 and 8 pm
Across all the parks we cover, that three-hour window holds the most Straw Belle sightings with a recorded time, and about 6 in 10 of them come between 6 am and 6 pm: it is most active around dawn and dusk.
Among the best
Of the 2 parks where we can rate Straw Belle sightings, Pyrénées National Park ranks 2nd at under 5%, level with the leaders once rounded. The best odds are in Cévennes National Park (France, under 5%).
GBIF citizen-science records
It is estimated from how often the Straw Belle is recorded against all the insects logged in Pyrénées National Park (10 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.
