Female Common Palmfly & Tawny Palmfly

[Common Mime]

I think the white patches on the underside of a female Common Palmfly is more obvious than a make which has a rather dark reddish brown underside. This is based on my observation for the past one week below my office.

The quantity of male seems like more than the female?

I find them like to walk on the leaves by dragging their abdomen touching the leaf. Any special reason?
