Peacock and Small Tortoiseshell really suffered and none were seen after early July.

Comma in common with the county trend boomed on the summer (hutchinsoni) generation

Although Speckled Wood and Ringlets suffered the rest of the browns in a large part made up for the other losses particularly Gatekeeper which tripled.
