This common butterfly prefers moist meadows and moist open woodland areas being favourites. In Cumbria therefore it has many such places to choose from. Best places are where its favoured egg laying, larval foodplants are and these are Lady's Smock, Garlic Mustard, Hedge Mustard and Water Cress.
Where to look
Wet meadows, moist woodlands, hedgerows and wide roadside verges particularly those in north Cumbria. The marshy margins of many of our lakes can also hold large colonies.
When to look
This is one of the first to emerge from pupation in early Spring, from mid April right through until mid-September.
