Chris has sent us this recent photo taken at Luscombe Valley Nature Reserve showing a female Clouded Yellow form helice.  Some 10% of female Clouded Yellows are of this pale variety with their colour ranging from a soft lemon yellow to white.  Their distinctive underwing pattern is similar in both the normal and helice forms.  So far this year Dorset Butterfly Conservation has received 114 reports of sightings of Clouded Yellows (including of the form helice).
