Considering your location, the butterfly could be a black swallowtail or an Ozark swallowtail.

The milkweed is swan plant from South Africa.

Swan plant = hairy balls. Hairy balls is a recent American marketing gimmick.

The last pic is lavender, the second ti last is purple globe aromath or something(Lol) and swan plant

What threw me off about the swallowtail is that it looks very different from one I photographed a couple months ago:

I forgot I took some better pics the other day with my camera. The one in the OP was taken with my cell phone. The butterfly hung around my yard for quite awhile, so I ran inside and got my camera. It was like he was showing off for the camera!

Sorry about the earlier poor quality photo. Here are some better ones from my camera:

Here he is with a friend. Anyone know if she's a Painted Lady or American Lady?

Jacob Berg, I thought the blooms looked like lavender, but I've only seen lavender with green foliage. Love the silver foliage!

The one in the first picture looks like a Pipevine to me. The three below look like Eastern Black Swallowtails. I can't see colors near the end of the tail. If so, then very probably Black Swallowtails. My first impression is that the orange and black one in the final pic is a Pearl Crescent.

Very nice pictures; thanks for posting them.

With the better followup pics, the first one is a black swallowtail. Ozark hindwing is different.

As for the black/blue swallowtail, it is not a pipevine. I think it is a female dark form eastern tiger swallowtail but spicebush is a possibility.

Thank you so much everyone! I'm obviously not very good at identifying butterflies! LOL Now that I see what a big difference the pictures quality is with my camera, I think I'll stick to taking butterfly photos with my camera instead of my phone.

I looked through my phone and I do have some more photos of the blue butterfly that might help with the identification.

I wish I had used my camera instead of my phone, and gotten a better sideview as well. I chased that baby all over the garden trying to get a good picture that wasn't just a blur. I'm sure I was quite a sight. He/she was VERY skittish and would hardly stay in one place long enough for me to get a good picture, whether it be with camera or cell phone.

3rd plant looks like a gomphrena to me.

This is a dark form female eastern tiger I raised in 2010 and eclosed in May 2011.

The one you found has more blue than mine. There is one on this page that I'd say has more blue than yours.

Wow, that's quite a variance on that page. The 4th pic down compared to the 7th one doesn't even look like the same type of butterfly. I think you're right though, KC Clark. Seems like the other swallowtails have white spots along their bodies, but the black tiger swallowtail just has one white spot at the bottom of her body, at least that I can see.

Take a peek at the last tiger swallowtail on this page. It's the female who cannot decide whether to be yellow or dark form. ;)
