Rare
Under 5% of wildlife watchers report a Colostygia aptata sighting in Pyrénées National Park on a given day, based on 7 verified sightings from GBIF citizen-science data from 2019 to 2026. It is the 1026th 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.
July
In that month about 10% of wildlife watchers report a Colostygia aptata in Pyrénées National Park on a given day, against under 5% in August to June, the lowest months.
Between 10 pm and 1 am
Across all the parks we cover, that three-hour window holds the most Colostygia aptata sightings with a recorded time, and about 8 in 10 of them come between 6 pm and 6 am: it is mostly seen at night.
4th of 4
Of the 4 parks where we can rate Colostygia aptata sightings, Pyrénées National Park ranks 4th at under 5%. The best odds are in Mercantour National Park (France, about 10%), Vanoise National Park (France, about 10%) and Hohe Tauern National Park (Austria, about 10%).
GBIF citizen-science records
It is estimated from how often the Colostygia aptata is recorded against all the insects logged in Pyrénées National Park (7 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.
