Silver-washed Fritillary Argynnis paphia
Post-hibernation larvae, feeding well and growing, to pupate in late spring and produce butterflies this season.
Feed on Violet or Pansy leaves – best kept on potted food. Make sure that, if you buy potted foodplant, there had been no insecticide used to produce them!
Keep hibernating larvae in leaf litter, in a plastic box in a very cool place for the winter. They wake in January/February and then need to be enclosed inside a sleeve, on potted violet.
