yeah, to be on the safe side, unless you want to take pics and have them id'd you can just leave them out all together. That said...there is one that you can safely feed and are real pests - army and cutworms - ICK.. they are gross, soft bodied, Charlie'd love 'em 
When it comes to butterflies and moths you might be asking the wrong person. I would never feed a butterfly to any of my animals and will not feed any of the wild silk moths (luna, cecropia, polyphemus, buck moth etc.) either because I raise them. I will only feed medium to small moths I gather at the porch light.
General rule, as I have said, always stay away form black/orange/yellow/red combinations. It is nature's rule of thumb to warn predator. NEVER feed a monarch butterfly or larvae, lightning bug, milkweed beetle, etc. Some of these are mimics and are not toxic, but unless you know exactly what you have...
