I have an inner city allotment, it's been there years and was originally a walled garden for one of Grainger's last houses. I watched a Wall warming up, in the sun, last summer, on the garden wall. But there was just one and they are declining rapidly, nationally. None this year, but there have been more Small copper and many Six-spot burnet moth. The Meadow brown I found in the gutter dead, took it home and scanned it. It was the most common butterfly at my base camp, but only half the size, there, of its city brethren. More delicately coloured too.
