When the sun shines these rare gems fly!
Unfortunately the weather has not been overly kind so far, however they are being seen with increasing frequency each sunny day.

So if swallowtail butterfly is on your 'want to see' list come down to the fen on a warm sunny day in the next couple of weeks, you may be rewarded with one of these beauties
