The one that fell can be secured c a bit of Super Glue, or so I've heard.
The other I would not move if you can help it, but stretch out the burlap on the wall c the chrysalis vertical, head pointing up. I would do this after it cools down a lot and the bugs, spiders etc settle in for the Winter.
If they do go into diapause, then you can leave them s a top for the Winter. They can then hatch in the Spring and not be trapped.

Any time I have one that falls, I place it in a small wicker basket.
The sides are rough enough the butterfly can climb. It is even better if it has a handle, but if no handle make sure the sides of the basket are 3 to 4 inches high, so the wings have room to hang while drying.
It is late enough in the season, they may overwinter.

You don't have to worry about reattaching them - they can eclose just fine laying on the bottom of the container. They do need to hang though, so get a stick and position the bottom resting very close to the chrysalis, and the top leaning against the side of the container. The stick needs to rest at somewhat of an angle so they have a place to hang and pump their wings. Or use a stick with little branches. I've done this many times, and they have no problem finding the stick :) Depending on the size of your container, those long wooden stir sticks from Starbucks work well too! Or pick up a paint stir stick and trim to size.

Oh, good. So there's a lot of wiggle room regarding positioning and whatnot. I hoped so; I figured that in nature the chrysalises must get knocked down from their little perches all the time and I assume that those butterflies hatch unless they're sitting in water. Thanks for the advice.
