I know we've kind of gotten onto the subject of feeding humans, but if you're feeding caterpillars, be aware that the BT poison that kills them is considered organic because it's a naturally-occurring bacteria. When I ran out of food for my Black STs I bought organic parsley from Publix (grocery store here in the south) and just hoped for the best. So far I've used theirs several times and they've been fine. They eat a lot more of it because you know the nutrition starts to fade as soon as you pick something so by the time it gets to the grocery store...let's just say those caterpillars ate a LOT more to grow to normal size than they would if I had plants in the ground. For the record, I grow rue to feed both the Giant STs and the Black STs. Florida gets a little hot for herbs, although we grow them every year at the museum where I volunteer. It just seems like the parsley (and especially the dill) start to fade from the heat just as the caterpillars are peaking.
