Butterfly newbie here. Was hoping if anyone can identify the species of butterfly these cats are? If can't and you know anyone who can please tag them so they see this thanks! I found these guys on my broccoli -hundreds of them! I removed as many as I could plus one cool green guy, and put then into some other plants in the front garden that I don't really care for . I also found some yellow eggs and several pupas but I didn't photograph them. I left the pupas on the broccoli. If anyone can ID these guys it would be a great help! Thanks! Oh also I'm in SW Ireland, Europe if that's any help! Thank you!
