Pupal mating

Male Zebra Longwings Surrounding Female Zabra Longwing Still in Chrysalis

This is not a mirror image. It is two male zebra longwing butterflies competing to be the first mate of a female butterfly that has not yet emerged from the chrysalis that is hanging between them. Not all butterflies do this .... but these sometimes do. It's called pupal mating. I will write more on this later.
