Hylobius abietis or the large pine weevil is a beetle belonging to family Curculionidae. This species is widely regarded as the most important pest of most commercially important coniferous trees in European plantations. Seedlings planted or arising from natural regeneration (germinated seed-fall) after clear felling operations are especially at risk. The adult weevils cause damage by eating the bark of seedlings around the 'collar' of the stem, thus 'ring-barking' the tree seedling which usually results in its demise.
The adult weevils are approximately 10–13 mm (0.39–0.51 in) in length (without beak/snout) and are dark brown with patches of yellow or light brown hairs arranged in irregular rows on their elytra. The legs are black or deep red with a distinctive tooth on the femora and at the end of tibiae.
The full grown larvae are 14–16 mm (0.55–0.63 in), typical for weevils, apodial, curved and are whitish, with brown head. Adults can be found all year long although they usually hibernate during the cold winter months. New adults ready to reproduce are attracted to freshly cut stumps of conifers. Eggs are deposited singly (one or two per day... Wikipedia →

Rare
Under 5% of wildlife watchers report a Large Pine Weevil sighting in Pyrénées National Park on a given day, based on 8 verified sightings from GBIF citizen-science data from 2019 to 2026. It is the 869th 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 September
In those months about 10% of wildlife watchers report a Large Pine Weevil in Pyrénées National Park on a given day, against under 5% in June–August and October–April, the lowest months.
Between 5 and 8 pm
Across all the parks we cover, that three-hour window holds the most Large Pine Weevil sightings with a recorded time, and about 7 in 10 of them come between 6 am and 6 pm: it is a daytime animal.
7th of 7
Of the 7 parks where we can rate Large Pine Weevil sightings, Pyrénées National Park ranks 7th at under 5%. The best odds are in Cairngorms National Park (United Kingdom, about 20%), Tatra National Park (Slovakia, about 10%) and Hohe Tauern National Park (Austria, about 10%).
GBIF citizen-science records
It is estimated from how often the Large Pine Weevil is recorded against all the insects logged in Pyrénées National Park (8 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.
