A friend has sent me a sketchy picture of a blue which appears to be egg laying on black medic on her lawn and wondered whether it could be Adonis Blue. We discussed food plants and how I thought it was more likely to be common blue and I sent her the picture from here highlighting the difference in the wing margin on the males of both species. She then said it looked more like the Adonis picture at which point I realised we were talking about a butterfly which appeared to be bright blue and therefore male.
Regardless of the species confusion which I'd prefer to park for now (hehe) the question is whether egg laying behaviour is ever observed in males or whether she should take a drive to Barnard Castle to check her eyesight because clearly supersavers have been letting her down
Hope everyone is well
Cheers
