are they mating? if yes then the male looks rly old.

It is not unsual for the male of most species to have enough energy for one last ride.

This raised the interesting question on whether in most lepidopterans the sex ratio will be skewed in favour of the female.

Fantastic details and colors! I've only seen them in the Butterfly garden, never in the wild.

I not be very good at this, but I do recall that another contributing factor may be that the males eclose 1st, before the females do. I have observed that for the leopard lacewings, that the males tend to eclose a day or two before the females do. However, as for the leopard lacewing case, the sex ratio is skewed in favour of the male.

My limited observation on the Tawny Coster ended with only males emerging from ten odd pupae.
The Raja Brooke's Birdwing had also been bred with a ratio of 2:1 male to female.

Pics of mating pairs often show a tattered male with a pristine female, but this probably shows a successful & experienced male, and not that males are low in number.
Males often fly around hostplants waiting for freshly eclosed females to mate, and when the females are unable to fly away.

They are here, Monique. I've seen them in Maenam, down Soi 5!
