Each species of butterfly behaves differently moments/minutes before they join to copulate. Watching a male Monarch physically force a flying female down to the ground is a bit much, others come together gently, and with apparent total focus.
This pair of Gulf Fritillary butterflies were in the tall grass when I found them at the Butterflies & Blooms Briar Patch Habitat in Eatonton, Georgia. Studying the photo convinces that this male and female are gently preparing for action to produce a new generation of Gulf fritillaries. Not suite which is the female or which is the male. I am sure that those flashes of white, nicely reflecting the morning light, are bedazzling.
Splendor in the Grass, this.
