A quick rifle through the trap this morning and 11 pale form Silver Y's, so I am pretty sure the weather front did bring saharan dust with it. It was the right colour too, orangey yellow. Also here's a snippet from Atropos "Night of 26 June: 1 Humming-bird Hawk-moth. Substantial falls of desert dust reported in Lizard village and Helston."
Nothing else of great interest, although a few potted up to look at later.
