I found another larva this morning on the milkweed in the garden and a egg! The egg should hatch in a couple of days.
The larva that I found is about 5 days old. I left it on its leaf and tore around it to bring it inside. I added another juicy one to encourage it to eat.
I do rinse the leaves off that I bring in from outside and dry them. I also rinse the 'milk' off the cut area and either wrap it in wet paper towel, rest it in residual moisture in the jar, or put it through plastic wrap to sit in water.
These three larvae are really making short work of this cluster of leaves I brought in yesterday. One of these caterpillars isn't doing so well. Yesterday it looked like all its skin didn't shed off as pieces of it were still attached. It spent most of yesterday lying on the paper towel on the bottom of the 'Castle' so I put it on a fresh leaf. It lay there for the rest of the day - not moving much or eating. Then this morning, I found it with these other two. There is still some flaky loose skin attached. Time will tell if it thrives and makes it to the pupa stage.
The eldest larvae should be pupating any time now. They're getting really big. Soon they'll climb to the top of their enclosure and begin attaching themselves in preparation for shedding their last skin and making a chrysalis.
