Adventures in Caterpillar Care (5)

Continuing my caterpillar care experience…

I never underestimated the amount of sweet gum leaves for the luna caterpillars again…but it got easier as the week progressed because more of the caterpillars were making cocoons so not as many leaves were required. The bin is very messy when a lot of caterpillars are beginning to make their cocoons since they expel waste and water before they begin the process. The paper towels in the bottom of the bin made clean up easier but it had to be done at least once a day. The cecropia caterpillars were finally all past instar 1.

Some of the luna cocoons were attached to the racks I had used to support the leaves, so they are in my first group of cocoons – inside a mesh cage that will contain the luna moths when they emerge.

By the end of the week the luna cocoon production was waning. I purchased 2 more mesh cages and gave 5 cocoons to my daughter with one of them. The other cage and 3 cocoons went to the family that owns the sweet gum tree that provided a lot of the food for the caterpillars.

Finally – I had 4 remaining luna moth caterpillars (all instar 5) and 3 cecropia caterpillars (1 instar 2 and 2 instar 3). It took them to the Butterfly House to use on the caterpillar display table.

I have the mesh cage and 3 bins (each with cocoons that were made at roughly the same time). There are about 35 cocoons. Most of the caterpillars I had at the beginning made it to the cocoon stage – very different than would happen in the wild with birds and other predators around. The moths should emerge in 2-3 weeks…lots of luna moths. I will take some of them to the Butterfly House and release others near sweet gum trees…hoping to feed a few young birds and maybe establish a luna moth population too.

The luna cocoons emit sounds periodically…giving me confidence that the pupa inside is viable and developing. I am looking forward to the opportunity to see so many of them emerge!
