Skeletonised leaves on one of our apple trees, which enclosed a web with a mass of greyish-yellow caterpillars with black heads and black spots. They reminded me of the bird-cherry ermine moths that defoliated a whole row of bird cherry trees near here last year. I think these are apple ermine caterpillars.
