This rather tatty moth found in a chalk grassland meadow - some kind of noctuid?? - had a strange growth attached to the base of its abdomen. It looked like a cylindrical sac full of egg-like structures and one "egg" seemed to be coming out. Maybe it's a parasite of some kind (though I can't find any records of moth parasites with this form) or a deformity of some kind... - like an ovary developed externally... Can anyone ID the moth or shed light on what the growth is?? The close up makes me feel queasy to look at... The poor thing seemed weak and could barely fly.
