Dave tells us:
A quick walk along the riverbank of Sturminster meadow on 19/8 /18. No sign of any second brood Small Tortoiseshell larval nests but came across two male Small Coppers battling for a territory. The winner then posed nicely for a picture. Also flying were Common Blues.
There are typically 2 or 3 generations each year, depending on the weather, with 4 generations in extremely good years. The first adults emerge in May, occasionally at the end of April, with the last adults being seen around the middle of October.
