If it was pale yellow then I would say a male Brimstone- the new generation are appearing now.
Clouded Yellows can be seen in good numbers at this time of year when there has been a good immigration. This year has been one of the worst on record for many insect migrants + they are very thin on the ground generally; this will be my second year of not seeing one in the UK.
