That stalk won't last the Winter. I might have to start getting creative.

I bring them in and raise them. That one looks to be in its last instar and doesn't have much longer before forming a chrysalis! Don't worry about it forming on the dill - they wander away to find an appropriate spot.

Just FYI, though, a wasp or spider may eat it before it can form the chrysalis. Wasps, especially, LOVE them.

There are lots of bees around this part of the garden, but I haven't seen many wasps or spiders.

You could bring it in, if you're willing to provide a lot of dill and some branches for it. They're really easy to care for (if you're so inclined) and there are good resources online to help. If not, that's completely understandable. Bringing bugs into the house isn't everyone's thing, for some reason.

Basil, thyme, rosemary, marjoram, oregano and, of course, dill. Lots and LOTS of dil. Didn't know it attracted butterflies!

I also grow quite a substantial amount of Milkweed for the Monarchs and Sunflowers for the birds - especially the yellow finches.

They need our help, and they definitely reward us with their beauty, don't they?

If you get too many caterpillars and they run out of food, you can feed them store-bought parsley. I've done that many times.

I have a nice Passion Plant.

When you're cutting up fruit, save only the juice and scraps for the butterflies.

which was mainly about the monarchs, but at the end she spoke about the Swallowtail - which btw is the NJ butterfly.
She said she had not seen many this year. I have not either. I don't have dill, but I used to have bunches on my Rue.

Really a great plant all around, especially in a mass planting. About as bulletproof as you can get.

Just make sure it's the non-hybridized type, as the hybrids don't create pollen. I just start them from seed.

I'm always weeding around this flower bed, and I've never seen caterpillars, before. I'm pretty geeked, right about now.
