I spent a few hours yesterday morning looking around the northern end of the Shapwick Heath reserve and in particular, the area of woodland accessed on the right just a couple of hundred yards in from the main road.  Unfortunately I didn't find the hornet moths mnentioned by Paul Cook but I connected with brimstone, gatekeeper, what I assume were large whites (but shouldn't they have 2 spots??), red admiral, ringlet, small tortoiseshell and lots of rather tatty speckled woods.  In addition I saw but couldn't photograph silver-washed fritillary, peacock and at least one other variety of white butterfly.

Shapwick shield bugs

On the bug front, I encountered birch and forest shield bugs and a red spotted plant bug.  The green shield bug is from a few days ago at the Ham Wall end of the reserve.
