I found it yesterday on a volunteer dill plant that grew up in the pole
beans. I thought it was a Monarch; they look very similar. Today it
has almost doubled in size already, and the dill plant is just about
gone. I might need to move it to another dill plant, or that 5 foot
tall carrot plant that is blooming. I don't know if they like to be
moved... It's not gonna eat my beans if I leave it alone and it runs
out of dill, will it? The beans would be a nice protected place for it
to pupate. It's odd that there's just one.

it will prefer dill if it spent it's first couple instars on
dill. it may eat the carrot (or Queen Anne's Lace), but i've
found they really prefer the original food plant they started
on. it won't touch your beans.
swallowtails deposit eggs one at a time on several different
plants in a 50-100' radius (maybe even wider. i am basing this
on my observatios in my yard, which has a lot of swallowtail
host plants). it's a good survival stratagy since only one
caterpiller per food plant means they're both harder for
predators to find & also likely to each have enough to eat.
does your caterpiller have the stinky orange horns that pop
out when touched?

It wasn't there again today
The host resolved to NSA.

I couldn't find him this afternoon. He's either moved on, or been eaten
by a bird. I looked on the nearby (very nearby) dill plants too.

if he was around 1.25" long when you saw him, he's gone now
because he's pupated
it's unlikely a bird ate it, as the stinky horns also taste
bad. my chickens leave them alone & not much gets by them.

I thought that might be the case, because that's how big it was
yesterday. They don't bury in the ground do they?

There are several types of swallowtail butterflies. I
suspect you have a Black Swallowtail though. Maybe:

http://home.att.net/~larvalbugbio/swallowtails.html

http://www.butterfliesandmoths.org/species?l=1356

http://insects.tamu.edu/fieldguide/cimg266.html

If so the scientific name is "Papilio polyxenes asterius".
Use that and a search engine and you can find a lot more
info.

I've been watching two similar caterpillars on some parley we have in
a pot on our deck.

One caterpillar was larger than the other and just yesterday I noticed
it crawling out of the pot. I followed it across the deck (it "jumped"
off the edge) and it crawled into a dense planting of climbing
hydrangea. I expect it will be pupating in there.

After another day of eating, the second caterpillar is almost as big
as the first one, so I'm expecting it to crawl off soon.

I was lucky to catch the first one in the act of making his get away.
