I think the Pieris sp. all hibernate as pupae and it would normally
take a prolonged warm spell to make them emerge - though it isn't
unheard of to get them emerging early.

The only other alternative is a Brimstone (Gonepteryx rhamni), which
do hibernate. Males emerge from hibernation on sunny days - even quite
cool ones. Females, which look more like a 'white' at a distance,
emerge much later in the year but it could always have been disturbed
and forced out prematurely(?)

Best wishes,
