Liparus glabrirostris
In 3 days ~80% in a week >90%
Liparus glabrirostris, the butterbur weevil, is a beetle belonging to the family Curculionidae, named after its larvae's most common genus of host plants, butterburs. When threatened, it can exhibit apparent death, becoming temporarily unresponsive.
Butterbur weevils are one of the largest weevil species in Europe, with the adult weevils reaching an approximate size of 14–19 mm (0.55–0.75 in) in length. They are dark black with irregular patches of light brown spots on the abdomen and thorax. Less noticeable light brown hairs can also be found on the legs and head.
This species is characteristic to high altitude riparian woodland zones in the mountains of Europe. The butterbur weevil is native to Central Europe, from Spain to Ukraine. The species is most commonly observed in the Alpine and Tatra mountain range, and in the Bohemian Massif. Wikipedia →

Likely
About 40% of wildlife watchers report a Butterbur Weevil sighting in Tatra National Park on a given day, based on 55 verified sightings from GBIF citizen-science data from 2019 to 2026. It is the 3rd most-seen of the 142 insects we can rate there. Over three days the chance rises to about 80%, and over a week to over 90%, if each day is a fresh chance.
May and June
In those months about 50% of wildlife watchers report a Butterbur Weevil in Tatra National Park on a given day, against under 5% in March and October–December, the lowest months.
Between 3 and 6 pm
Across all the parks we cover, that three-hour window holds the most Butterbur Weevil sightings with a recorded time, and about 9 in 10 of them come between 6 am and 6 pm: it is a daytime animal.
Only Tatra National Park, in our data
Tatra National Park is the only park on Wallace's Line with enough records to rate Butterbur Weevil sightings: about 40% of wildlife watchers there report one on a given day.
Same family: Curculionidae
The closest relatives of the Butterbur Weevil that you can see in Tatra National Park (family Curculionidae, True Weevils) are Phyllobius arborator (about 20%), Otiorhynchus coecus (about 10%) and Large Pine Weevil (about 10%), with each one's daily chance of a sighting.
GBIF citizen-science records
It is estimated from how often the Butterbur Weevil is recorded against all the insects logged in Tatra National Park (55 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.
