Silver-Washed Fritillary (Argynnis paphia) lives in woodland edges across Palaearctic ecozone. It feeds on violet leaves only.
Fascinating facts about the Silver-Washed Fritillary
- The silver-washed fritillary stretches 54-70 mm from wingtip to wingtip, making it a medium-sized butterfly, yet the male is noticeably smaller and paler than the female. Its upperside dazzles in deep orange peppered with black spots, while the underside shimmers green with metallic silver bands that curve like brushed steel. This size gap and striking coloration help researchers tell the sexes apart in the field.
- Unlike most butterflies that lay eggs on their caterpillars' food plants, the female silver-washed fritillary climbs 1-2 m up a tree trunk and deposits each egg in bark crevices near violet clumps. Seitz recorded her starting "about 4 or 5 ft. above the ground" and spacing eggs "at intervalls of 1/2 to 1 m", spiralling up until she reaches roughly 4 m before moving to another tree.
- The life cycle of the silver-washed fritattery is timed to the seasons: eggs hatch in August and the tiny caterpillars immediately enter hibernation, emerging only in spring to drop to the forest floor and feed on violet leaves. After a months-long larval stage, they pupate among ground vegetation, and the adults take flight in June. In Europe the species is then on the wing from July through September.
- The silver-washed fritillary is capable of gliding high above the canopy at a speed. It prefers thin, sunny deciduous woodlands, especially oak groves, but will also settle in coniferous stands when needed.
- After a steep decline across the UK during the 1970s and 1980s, the silver-washed fritillary is now re-appearing in many of its historic sites.
