Rare
Under 5% of wildlife watchers report a Phytoecia nigricornis sighting in Vienna on a given day, based on 11 verified sightings from GBIF citizen-science data. It is the 838th most-seen of the 1406 insects we can rate there. Over three days the chance rises to about 10%, and over a week to about 20%, if each day is a fresh chance.
Any time of year
In every month with enough records, under 5% of wildlife watchers report a Phytoecia nigricornis in Vienna on a given day, so our monthly data shows no clear season.
Yes
Of the 2 cities where we can rate Phytoecia nigricornis sightings, Vienna has the highest daily chance: under 5%. Next come Moscow (Russia, under 5%).
GBIF citizen-science records
It is estimated from how often the Phytoecia nigricornis is recorded against all the insects logged in Vienna (11 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.
