Rare
Under 5% of wildlife watchers report a Nut Leaf Weevil 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 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.
May and October
In those months about 10% of wildlife watchers report a Nut Leaf Weevil in Pyrénées National Park on a given day, against under 5% in June–September and November–April, the lowest months.
Between 3 and 6 pm
Across all the parks we cover, that three-hour window holds the most Nut Leaf Weevil sightings with a recorded time, and about 6 in 10 of them come between 6 am and 6 pm: it is seen both by day and at night.
5th of 5
Of the 5 parks where we can rate Nut Leaf Weevil sightings, Pyrénées National Park ranks 5th at under 5%. The best odds are in Acadia National Park (United States, about 10%), Bavarian Forest National Park (Germany, about 10%) and Cairngorms National Park (United Kingdom, about 10%).
GBIF citizen-science records
It is estimated from how often the Nut Leaf Weevil 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.
