Tropinota hirta
In 3 days ~10% in a week ~30%
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 →

With luck
About 10% of wildlife watchers report an Apple Blossom Beetle sighting in Bucharest on a given day, based on 7 verified sightings from GBIF citizen-science data. It is the 218th most-seen of the 361 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.
April and May
In those months about 10% of wildlife watchers report an Apple Blossom Beetle in Bucharest on a given day, against under 5% in June to March, the lowest months.
Between 10 am and 1 pm
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.
12th of 12
Of the 12 cities where we can rate Apple Blossom Beetle sightings, Bucharest ranks 12th at about 10%. The best odds are in Antalya (Turkey, about 20%), Izmir (Turkey, about 20%) and Budapest (Hungary, about 10%).

GBIF citizen-science records
It is estimated from how often the Apple Blossom Beetle is recorded against all the insects logged in Bucharest (7 verified sightings), 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.
