Phyllobius arborator is a species of broad-nosed weevils belonging to the family Curculionidae, subfamily Entiminae. This beetle is present in most of Europe. The soil-living larvae feed on the roots of host plants, while the adults feed on leaves of deciduous trees and shrubs.
The adults grow up to about 10 millimetres (0.39 in) long and can be encountered from April through August. The colour of the body is metallic blue-green. Wikipedia →

Rare
Under 5% of wildlife watchers report a Phyllobius arborator sighting in Warsaw on a given day, based on 10 verified sightings from GBIF citizen-science data. It is the 373rd most-seen of the 580 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.
May
In that month about 10% of wildlife watchers report a Phyllobius arborator in Warsaw on a given day, against under 5% in June to April, the lowest months. That is one of Warsaw's wettest months, with about 75 mm of rain against 40 mm in February.
Between 9 am and noon
Across all the parks we cover, that three-hour window holds the most Phyllobius arborator sightings with a recorded time, and about 9 in 10 of them come between 6 am and 6 pm: it is a daytime animal.
2nd of 3
Of the 3 cities where we can rate Phyllobius arborator sightings, Warsaw ranks 2nd at under 5%. The best odds are in Saint Petersburg (Russia, about 10%).
GBIF citizen-science records
It is estimated from how often the Phyllobius arborator is recorded against all the insects logged in Warsaw (10 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.
