Checkered White or Cabbage White?
Has anyone raised Checkered Whites before? I collected a whole bunch of eggs on Hairy Bittercress (Cardamine hirsuta). They are starting to hatch, and I am sure most of them are cabbage whites. However, we did see a checkered white laying eggs in the area on the same plants. Are you able to tell the hatchlings apart? I can't find any pictures of hatchlings. The only thing I could find was a first instar picture. That picture shows a caterpillar with a black head. All the hatchlings so far have green or white heads.
Any info would be a help!
