Rare
Under 5% of wildlife watchers report a Beech Leaf-Mining Weevil sighting in Bavarian Forest National Park on a given day, based on 6 verified sightings from GBIF citizen-science data from 2019 to 2026. It is the 822nd most-seen of the 1115 insects we can rate there. Over three days the chance rises to about 10%, and over a week to about 30%, if each day is a fresh chance.
March–May and November
In those months about 10% of wildlife watchers report a Beech Leaf-Mining Weevil in Bavarian Forest National Park on a given day, against under 5% in June–October and December–February, the lowest months.
Between 3 and 6 pm
Across all the parks we cover, that three-hour window holds the most Beech Leaf-Mining Weevil sightings with a recorded time, and about 7 in 10 of them come between 6 am and 6 pm: it is seen both by day and at night.
Only Bavarian Forest National Park, in our data

GBIF citizen-science records
It is estimated from how often the Beech Leaf-Mining Weevil is recorded against all the insects logged in Bavarian Forest National Park (6 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.
