(I think I posted this in the USA by mistake.) My runner bean leaves are getting chewed down to a stub - fairly sure it's not slugs as the plants are in individual hosta haloes which have always worked well before, plus no slime trails. Wondered if it was wood pigeons but still happened when I put netting over. No caterpillars on the undersides of the leaves. Is anyone else getting this? (My broad bean leaves have holes in too but not as badly.)
