Both these pictures of the African Migrant (Common Vagrant) were taken in our garden. It was not uncommon to find them warming themselves up in the late afternoon sun amongst the autumn leaves, ready to settle for the night. On a hot summer day they could be found in a flurry around some Senna bushes (I think our common invasive S didymobotria, a food plant?) Or else in their rather mindless migration.
The top is a female (form florella.), I didn't know whether the bottom one was a male or a female (form pyrene.)
