Zwangspaarung

I have hand paired Papilio polyxenes and Papilio macheon oregonia.

They were both similar in apparent parameters-

those being angle of copulation, time of day and age, as well as before and after feeding

For me, it seemed easier in the late morning before feeding, with animals more than 1 day old.

I was a first timer, at the start it seemed impossible, but after sticking with it, I managed to end up with too

many ova and larva. The butterflies need gently held and simply press the abdomens together while slightly

squeezing to expose the genitalia, at basically a straight on approach, rather than an angle.

All that being said, it's still something that takes patience and experience, which I still lack somewhat.
