(1/1250th sec at f14. © David Hastings) DescriptionFamily: Pieridae Wing span: 69 - 76 mm This species became extinct in Britain in 1925, ending a decline which had begun in the early 19th century. The cause of this demise is a mystery, since its foodplants can be found in abundance in all of its former sites. It is found in most of Europe, but has become extinct in the Netherlands. It favours warm, sunny, bushy places, especially orchards comprising species of the larval host plants. There is one generation a year, with the main flight period in late June and July. The larva is the over-wintering stage. The larval foodplants are Blackthorn (Prunus spinosa) and most Prunus cultivars. Thistles are a favourite nectar source. Sightings
