Pretty Fritillary

The garden is livened each & every year by hordes of what I believe are a type of Fritillary. They seem to have carved a niche in this section of NE Bristol and are seemingly firmly established.
Always guaranteed to lift the spirits with their flutteryby antics and bush basking sun worshipping - a simple, yet somehow profound joy to witness.
They didn't adorn the newly opened bluebells (tinkling 2' below this shot of the graced honeysuckle) - at least not with me watching - as this would have combined both shots vying for today's blip spot.
A little searching and I'm now unsure that this is not a Speckled Wood - Pararge aegeria. Doesn't rhyme with Pretty though.. so I shall ignore such inconvenient data!
