Easiest way to breed Camberwell beauty

Greetings everyone,

I caught 5 Nymphalis antiopa adults. I might obtain a few other as well. Is there any way to tell if they have breed yet? I have a mix of 2 females and 3 males. They are post hibernation adults that have been living since June. They are all in great shape, though. I know what the host plants are but nothing much is blooming right now. Do they hold on to there eggs? Also, if anyone has information on this or Polygonia species (I have also obtained) please let me know.

Regards,

Ethan

I don’t think the taxonomy changed. By Polygonia I meant Nymphalis and Polygonia c-album. I have both. I will look on the web. Where can I get poplar this early?

Lately, it’s been around the mid 70’s which is warm for this time. Could have a hand in them breeding earlier in April than in may? How do they lay eggs in the wild since they are wild butterflies.

Well I guess I can forget about it. The adults seem to be dying. I don’t know anymore. Really. There must be something in the cage.

Thank you for all you help everyone.
