Please help me!! How do I learn to identify what type of swallowtail larva n eggs I have on my parsley, dill n fennel in my garden?? I have yet to find a site on the Internet that shows the different species in each stage of life!! I've read there are over 500 species of swallowtails. I'm sure living here in St. Pete Florida narrows down many of them but I'd love to find a site where I can see and compare the different stages of life of the swallowtails for some of the different species there are. That would be awesome!! Your pictures are beautiful and very educational!! I love it! ;)
