Possible
About 20% of wildlife watchers report a Buttoned Snout sighting in Biebrza National Park on a given day, based on 6 verified sightings from GBIF citizen-science data from 2019 to 2026. It is the 60th most-seen of the 97 insects we can rate there. Over three days the chance rises to about 40%, and over a week to about 80%, if each day is a fresh chance.

In that month about 50% of wildlife watchers report a Buttoned Snout in Biebrza National Park on a given day, against under 5% in March–April and June–August, the lowest months. December has too few records to rate.
Between 8 and 11 pm
Across all the parks we cover, that three-hour window holds the most Buttoned Snout sightings with a recorded time, and about 6 in 10 of them come between 6 pm and 6 am: it is seen both by day and at night.

GBIF citizen-science records
It is estimated from how often the Buttoned Snout is recorded against all the insects logged in Biebrza 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.
