In 3 days ~10%
Eumedonia eumedon, the geranium argus, is a butterfly of the family Lycaenidae. It is found in the Palearctic realm. This butterfly has been included in the genera Plebejus, Plebeius, Polyommatus and Aricia, but recent molecular studies have demonstrated that Eumedonia is a valid genus, different from the previous genera mentioned.
The wingspan is 26–30 mm. The butterfly flies from May to August depending on the location. The larvae feed on Geraniaceae species (genera Geranium and Erodium). Wikipedia →

Rare
Under 5% of wildlife watchers report a Geranium Argus sighting in Moscow on a given day, based on 6 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 a Geranium Argus in Moscow on a given day, so our monthly data shows no clear season.
Between 11 am and 2 pm
Across all the parks we cover, that three-hour window holds the most Geranium Argus sightings with a recorded time, and about 9 in 10 of them come between 6 am and 6 pm: it is a daytime animal.
Only Moscow, in our data
Moscow is the only city on Wallace's Line with enough records to rate Geranium Argus sightings: under 5% of wildlife watchers there report one on a given day.
GBIF citizen-science records
It is estimated from how often the Geranium Argus is recorded against all the insects logged in Moscow (6 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.
