The clouded yellow butterfly, colias croceus, is a wandering migrant butterfly to the southern half of the UK that often arrives from southern Europe in Spring and has a second summer brood that flies in August and September. Historically British winters have been too harsh for the clouded yellow to survive overwinter and establish a year round naturalised presence here, but climate change is in its favour and there have been recent indications that sucessful overwintering may be becomimg possible. This was my first and only sighting of this vibrant custard-yellow lively wandering butterfly and a lovely end to the 2013 butterfly season.
