It's not often that one goes out and sees three species of blue butterfly in Norfolk at the same place on the same day, but I've managed it a couple of times recently. It's been an extraordinary year for common blues, plenty of them about and all the more amazing given they had such a dire time last year. Holly blues are much more scarce, but still appearing in ones or twos. The revelation of 2013 has to be the chalkhill blues, so exquisite and I love the way they perch up and pose. The males are fabulously combative, chasing each other up into the air in fast and tight spirals before breaking off and dropping back down to bask or nectar again.
