Available during April and September. (Third party breeder). Once a garden visitor, with a wide distribution across the UK, the decline of this formerly common butterfly has been severe in the past few decades and it now appears to have 'retreated' to coastal areas of the British Isles. The striped, green larvae will feed on almost any grasses in captivity, but Sheep's- fescue, Cocks- foot and Yorkshire- fog will be particularly appropriate. There are two broods per year with adults taking to the wing in May / June and July / August respectively. Overwintering takes place in the larval stage.
