Not a favourite flutter with everyone, the Large White. Often called Cabbage White as they like to lay their eggs in large numbers under brassica leaves. The caterpillars can strip the leaves in no time at all.
My large Buddleia bush has produced a magnificent show of flowers this year and they have been attracting dozens of bumble bees and a few butterflies. At first I thought I was just filming a couple of white flutters but on watching the video I could see that the male, fluttering about, was trying to mate with a couple of females. The females are the ones with two black spots on each wing.
When the female opens its wings and raises the abdomen it is a sign of refusal as she has probably already mated. Source: Journal of Comparative Physiology - you may have to click on the Look Inside link to read the relevant section.
