Rare
Under 5% of wildlife watchers report an Orange Crest sighting in Moscow on a given day, based on 5 verified sightings from GBIF citizen-science data. It is the 992nd 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 an Orange Crest in Moscow on a given day, so our monthly data shows no clear season.
Among the best
Of the 2 cities where we can rate Orange Crest sightings, Moscow ranks 2nd at under 5%, level with the leaders once rounded. The best odds are in London (United Kingdom, under 5%).
GBIF citizen-science records
It is estimated from how often the Orange Crest is recorded against all the insects logged in Moscow (5 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.
