They were first seen in Britain in large numbers on 21st May, but the first time we saw any here in Scotland was 29th May. That evening we went for a walk along a country path near our home and saw at least half a dozen of these beautiful butterflies.
Since then we have seen fewer, and most have been flying past at such a speed that it was hard to be sure of the species, but this one conveniently perched on a bluebell flower.
Another was feeding on buttercup flowers close to the canal.
