A total of 253 painted ladies were counted on a single patch of bramble at Hickling national nature reserve in Norfolk this week, and Butterfly Conservation’s Dan Hoare reports that a significant immigration from Europe occurred over the past week as the hot spell collapsed.

The heatwave and southerly winds have also delivered rare moths, including the eastern bordered straw.
