September 2nd – The Darlaston Robins Pincushion Galls are looking really amazing right now – the one on the main ‘trunk’ (stalk? Branch?) of the wild rose is the largest I’ve ever seen, and still growing – now the size of a tennis ball, but elongated. On the outer leaves, the one that clearly misfired across multiple leaf nodes is causing odd, isolated patches of gall growth on leaves and twigs that look almost tumourous in nature.
This is an absolutely fascinating thing and I make no apologies for regularly featuring it. This is part of the wasp gall’s lifecycle and it’s absolutely stunning that such a tiny insect should co-opt and corrupt the growth of a plant to create such a host for its larva.
