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.
