Welcome to Steemit! I love butterflies! I've had a lot of luck attracting swallowtail butterflies to my work garden the last couple of years with parsley and carrots. I actually have swallowtail butterfly caterpillars in both right now in various stages of growth. They're really neat to watch developing.
That's great! I love to see the caterpillars and then it's so exciting if you find a chrysalis! I'll share my photos of my monarch caterpillars, chrysalis' and emerging butterfly at some point. I happened to be lucky and have them in my yard one fall.
I'm planning to do a post about my swallowtail caterpillars at some point. I have pics of them in multiple stages of development. Took a while for me to identify them last year after they first showed up. Thankfully I was cautious b/c I wasn't sure and just left them alone until they got big enough to make an id. I was watching for them this year. I have probably twice as many in this first batch as I had all year last year. I haven't actually found a chrysalis yet. I'll probably nerd out when I finally do and get all excited and take lots of pics lol
