There are far fewer than a few years ago. Perhaps as parasites catch up with them. I watched (a few years back) a couple of Ichneumons hovering near a colony of cinnabar caterpillars in my garden. They responded by flailing their rear ends around but the parasites just kept hanging in the air waiting their chance.
However, one adult cinnabar on Weds 24th June in a field behind the Griffin Inn, Barkisland.
