We have a little butterfly here called a skipper thats easy to catch and the chams love them. I fed a dragon fly that emerged from my pond and my Fischers loved it! Plus a huge grasshopper he had to hold on too, it was so good! I fed the grasshopper for a few days first.
oh right i forgot about skippers, most of those are non-noxious too...and so are leaf butterflies, they are bright orange inside but brown outside so the bright colors are just a deterrant theyre not toxic
