Was cycling along planning not to go far and didn't (still in pain when I got home) and just as I was still on the River Lea I spotted something.
Small light bluish butterfly fluttered past me and up towards a bridge. At these points my brain now says right a Blue Butterfly or a Hairstreak Butterfly! I walks up onto the bridge and managed to see more than half a dozen of them and then realized they was n a Holly Bush, lol. They were also mating and laying eggs.
