I spent several minutes considering whether to actually purchase any of these things. I thought the little tote bag would make a nice purse, but I would need to lengthen the straps somehow, and make a way to close it (like that would ever really happen.)

It's the dawn of the second day of the little monarch's life. I found that he had enlarged the hole he made in the leaf last night, after which he made his way to another leaf, and was actively exploring when I took these pictures.
I wonder if he's just looking for a place to settle down, or is he not satisfied with what this plant can provide in the way of nutrition? Maybe he's trying to find the real milkweed. In any case, I decided I had better put him and his plant in a little enclosure to keep him from wandering too far.
It will be harder to observe him now, but it's better just to let nature take its course for the next few days, and then I'll open it up and see how he's doing.

One of the monarch eggs on the plant I'm observing. I knew it looked ready to hatch this morning, but I was not able to just sit and watch it all day, so I just kept checking on it when I could and sure enough, I managed to just miss the actual hatching.
Here's the little guy eating his first meal: his egg shell.
At last check, he had finished eating the shell, and had also eaten a teeny little hole in the leaf, but it's too dark to take his picture any more today. (The pictures above were taken outside in the sun.)

I soon realized she was actually ovipositing, laying eggs, on these little plants. But what are these little plants? They don't look like the regular Asclepias curassavica milkweed plants that the Monarchs use at the arboretum.
My first thought was that this poor old, dying female was trying to put her last few eggs somewhere, anywhere, because she could no longer fly to where the proper host plants were.
Here's a shot of one of the little weeds next to my hand, for a size reference. The little white spots you see are not monarch eggs, but the white milky sap that oozed out when I picked a leaf.
So, hmmm.....maybe the butterfly knows something about this plant that I don't.
A little farther along on the same trail, I found these same plants supporting small colonies of yellow oleander aphids. This is the same aphid that commonly infests the milkweed plants (A. curassavica) that the monarch caterpillars love to eat.
So, I sought an ID from our ever-knowlegable plant curator, who quickly recognized it as Araujia sericifera, an invasive vine that is from the same milkweed subfamily: Asclepiadoideae. He said they must remove this pesky plant, or the vines would grow and grow until they overtake even the tallest trees in the arboretum. So don't expect to save it for the caterpillars. I didn't expect that, I assured him. I just wanted to find out if it really was a monarch host plant. Besides, so far I had only just seen one tattered old butterfly laying eggs on it. I hadn't seen any caterpillars...
Today when I went to collect a few of the plants that had eggs on them, I found a small caterpillar on one. I am going to try potting up a few of these weeds (taking care to make sure they don't escape and take over my whole back yard, of course) and try to see if a caterpillar will actually grow well on them. If they do, it would at least be another food source for the teachers who are always running out of milkweed for the caterpillars in their classrooms.

I'm guessing it was a female, by the head and body size. And she had a sowbug-killer spider in her jaws. The spider was probably looking for a new place to hide under, and the lizard was quick to grab herself a little breakfast.
And nice enough to sit still while I ran for my camera.
And that's the end of the tale. I told you it was short :)
