Tropinota hirta
In 3 days ~50% in a week ~80%
Tropinota hirta, also known as the "apple blossom beetle" or "hairy rose beetle", is a species of beetle in the Scarabaeidae family, native to the Old World. It is not found in North or South America. Common from April onwards on flowering plants, whose parts it feeds on, this polyphagous rose chafer causes serious damage to crops and ornamental flowers.
The larvae live in the soil and feed on roots (often dead ones) without causing significant damage. Wikipedia →

Possible
About 20% of wildlife watchers report an Apple Blossom Beetle sighting in Biebrza National Park on a given day, based on 8 verified sightings from GBIF citizen-science data from 2019 to 2026. It is the 40th most-seen of the 97 insects we can rate there. Over three days the chance rises to about 50%, and over a week to about 80%, if each day is a fresh chance.
April and May
In those months about 30% of wildlife watchers report an Apple Blossom Beetle in Biebrza National Park on a given day, against under 5% in March and June–October, the lowest months. December has too few records to rate.

Across all the parks we cover, that three-hour window holds the most Apple Blossom Beetle sightings with a recorded time, and nearly all of them come between 6 am and 6 pm: it is a daytime animal.

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