The silver-washed fritillary (Argynnis paphia) is a common and variable butterfly found over much of the Palearctic realm – Algeria, Europe and across the Palearctic to Japan. The silver-washed fritillary butterfly is deep orange with black spots on the upperside of its wings. It has a wingspan of 54–70 mm, with the male's being smaller and paler than the female's. The underside is green (verdigris) with a metallic gloss and broad silver bands which are partly curved, hence the name silver-washed. In the male the forewings are rather pointed whereas in the female they are more rounded. On females of the minority valesina form, recurrent in most European populations, the ground color is not fawn but grey with greenish reflections. The caterpillar is black brown with two yellow lines along its back and long reddish-brown spines.
The male possesses scent scales on the upperside of the forewing that run along veins one to four as three distinct scent-streaks. The scent produced from these scales attracts females and helps to distinguish it from other species.
Adults feed on the nectar of bramble, thistles, and knapweeds, and also on aphid honeydew... Wikipedia →

GBIF citizen-science records
It is estimated from how often the Silver-Washed Fritillary is recorded against all the insects logged in Yekaterinburg (51 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.
