Andrew photographed this Clouded Yellow, helice form, at Southbourne Undercliff on 28/09/17 and says:

Hurray, just had my first UK Clouded Yellow form helice for 2017!

The form helice only occurs in the female of the Clouded Yellow  and is similar to the much rarer immigrant, the Pale Clouded Yellow.
