that would be great if these are females I have 5 pupae and if one pair comes out at the same time I will try to mate them, but thats very difficult I guess,specialy now that its quiete cold in Europe, to get a female laying eggs. Robert
Although the perspective of the photo makes it difficult to tell, the top pupa looks like a female, the other's probably a male. As with most Papilionidae, they should be easy to hand-pair as long as the male's well-fed for 2 or 3 days and you get it hot enough first. Obviously the ambient temperature in Europe makes it difficult, and can you find a suitable foodplant?
Hi Bob I dont have the natural foodplant (it didnt even smell like a Rutacae-Citrus) and looked more like a Fraxinus,the leaves have the shape of a Ash tree like in Europe(ofcourse it must have been a Rutacae) Some books write that they lay eggs on the young leaves of Citrus(Orange) ,that would be not a problem for me, I have 3 orange trees(now occupied with some caterpillars of Papilio andraemon ssp.tailori ;D ) But it would be worth a try, I know the pairing is the smallest problem, its the temperature now that would be the problem to stimulate a female to lay eggs.

I find that semi-tropical species will lay well under plastic (e.g. a propagator) with a light above. Of course it gets very hot so they need feeding very regularly. This way they usually have to lay on cut food which isn't ideal but it's a good way of getting plenty of eggs quickly.
I think the larvae are likely to present bigger problems.
