Rare
Under 5% of wildlife watchers report a Saperda perforata sighting in Moscow on a given day, based on 7 verified sightings from GBIF citizen-science data. It is the 841st most-seen of the 1111 insects we can rate there. Over three days the chance rises to about 10%, if each day is a fresh chance.
Any time of year
In every month with enough records, under 5% of wildlife watchers report a Saperda perforata in Moscow on a given day, so our monthly data shows no clear season.
Between 7 and 10 am
Across all the parks we cover, that three-hour window holds the most Saperda perforata sightings with a recorded time, and about 6 in 10 of them come between 6 am and 6 pm: it is seen both by day and at night.
Among the best
Of the 2 cities where we can rate Saperda perforata sightings, Moscow ranks 2nd at under 5%, level with the leaders once rounded. The best odds are in Vienna (Austria, under 5%).
GBIF citizen-science records
It is estimated from how often the Saperda perforata is recorded against all the insects logged in Moscow (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.
