We know our Alners Gorse Butterfly Reserve is pretty special, but we didn’t expect this! Mark Pike is a regular visitor to the Reserve and says he at first thought this was a Common Blue aberration, but when he spotted the tails, he know otherwise. Seen on 15/08/2019.
This is the second recent report – another was seen near Weymouth on 03/08/2019. If you want to read more about this previous sighting and what our Records Officer said about the species, click here.
