For August, the target species is Phyllonorycter coryli (Nut Leaf Blister Moth). This moth makes highly conspicuous silvery blisters on the upper surface of hazel leaves and is perhaps the easiest leaf-miner species to identify.

A bonus point will be award to whoever finds the most mines on a single leaf, a challenge started by Norman Lowe:
And have you tried the P. coryli challenge!? Started by Norman Lowe from Brecon - whats the most mines of coryli you can find in one leaf!? You’ve got a ‘fourer’, I’ve managed 20 once can anyone find more?
