Look out for the rare Autumn Squill Prospero autumnale hiding in the grass. This one was photographed on the side of a rural track in Vienne, near Vicq sur Gartempe. They are related to Bluebells and Star of Bethlehem.
There are lots of big impressive flies buzzing around in August. This one is the Giant Tachinid Fly Tachina grossa, nectaring on Hemp-agrimony Eupatorium cannabinum growing in a ditch, but you could see horse flies with their dazzling stripey eyes, or hover flies mimicking hornets or even robber flies, the fiercesome hunters that rival dragonflies in their near perfect kill rate.
