Rare
Under 5% of wildlife watchers report an Amphipyra perflua sighting in Moscow on a given day, based on 12 verified sightings from GBIF citizen-science data. It is the 608th most-seen of the 1111 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 an Amphipyra perflua in Moscow on a given day, so our monthly data shows no clear season.
Between noon and 3 pm
Across all the parks we cover, that three-hour window holds the most Amphipyra perflua 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 Amphipyra perflua sightings, Moscow ranks 2nd at under 5%, level with the leaders once rounded. The best odds are in Helsinki (Finland, under 5%).
GBIF citizen-science records
It is estimated from how often the Amphipyra perflua is recorded against all the insects logged in Moscow (12 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.
