Pieris bryoniae Zucht

Hello everyone,

Does anyone have experience with breeding pieris bryoniae. I am having difficulties with breeding them.

Thankful for any tips and tricks

Hi,

I tried to breed them in a climated greenhouse (approx. 20°C) in regular butterfly cages. I faced a high mortality (I think most of them lived abround 3-10 days). I also have the problem with accessibility of host plants. Since pieries bryoniae is living in a higher altitude than i am, I cannot easily get feeding plants. However, I managed that one female layed around 10-15 eggs on a brassica oleracea leaves.

From the 15 eggs around 10 of them disappeared, I don't know if the dropped somewhere or what happened. Then I think some of them hatched but I didn't see any larvae, so they might not feed on brassica oleracea? does anyone knows if the larvae feed on brassica oleracea?

At least one of the eggs were infested with Diadegma semiclausum. And two eggs are still unhatched but the leaves are getting moldy, so I am not sure how to handle the situation.

Basically, a lot didn't really work out so I am thankful for any advise or if someone has any experience.

Cheers!
