Argynnis paphia is a common and variable butterfly found over much of the Palaearctic ecozone – Algeria, Europe, temperate Asia and Japan.
The Silver-washed Fritillary (Argynnis paphia) was in decline in the UK for much of the 1970s and 1980s, but seems to be coming back to many of its old territories.
The Silver-washed fritillary butterfly is deep orange with black spots on the upper side of its wings, and has a wingspan of 54–70 mm, with the male being smaller and paler than the female. The underside is green, and, unlike other fritillaries, has silver streaks instead of silver spots, hence the name silver-washed.
The Queen of Spain Fritillary (Issoria lathonia) is a butterfly of the family Nymphalidae.It occurs throughout the Palaearctic from North Africa to Japan.It is distinctly migratory in Western Europe, in Central and South Europe.
The adult is a strong flyer, and may be found anywhere but forests. Flight time is between March and October, size is between 38 mm and 46 mm, and is usually found at altitudes between sea level and 2700 m .
