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 →

GBIF citizen-science records
It is estimated from how often the Large Pine Weevil is recorded against all the insects logged in Tatra 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.
