Droplet Butterfly

Rain all day. Got to roll with it. I went out in search of droplet bugs and was secretly hoping for a droplet butterfly. I got soaked but lucky this afternoon. I found this green veined white clinging onto sheep's parsley. My pic of a droplet dung fly was better but I thought the butterfly was more blip-friendly. :)

I met Pheasy Boy, haven't seen him for a while. He strode towards me and came quite close. He was saying, "Woo, woo, woo, woo, woo, woo" very quietly without moving his beak. I can't find any reference to this vocalisation online.
