Xylocopa violacea
In 3 days ~10% in a week ~30%
Xylocopa violacea, the violet carpenter bee, is the common European species of carpenter bee, and one of the largest bees in Europe. It is also native to Asia. Like most members of the genus Xylocopa, it makes its nests in dead wood. It is not particularly aggressive, and will attack only if forced to.
The range of Xylocopa violacea extends from Europe eastward across Asia as far as central China, restricted to latitudes above 30 degrees. In 2006, Xylocopa violacea was reported from Cardigan, Wales. In 2007, it was found breeding for the first time in England, in Leicestershire. This follows a northwards expansion of its range in France, Germany, and the Channel Islands. In 2010 it was recorded in Northamptonshire and Worcestershire.
In India, any all-black species of Xylocopa are referred to by the common name "bhanvra" (or "bhomora" – ভোমোৰা – in Assamese), and reports and sightings of bhanvra are commonly misattributed to this species. However, this species is found only in the northern regions of Jammu and Kashmir and Punjab. Most reported sightings refer to any of several other common black Xylocopa, such as X. nasalis, X. tenuiscapa, or X. tranquebarorum.... Wikipedia →

Rare
Under 5% of wildlife watchers report a Violet Carpenter Bee sighting in Milan on a given day, based on 10 verified sightings from GBIF citizen-science data. It is the 207th most-seen of the 351 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.
February, May–June, August and October

GBIF citizen-science records
It is estimated from how often the Violet Carpenter Bee is recorded against all the insects logged in Milan (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.
