Liz,

I have raised a few anise swallowtails over the years. I have noticed that
if I collect first instars, they are sometimes parasitized by a wasp that
emerges from the second instar. I haven't noticed the wasp in older
caterpillars. So maybe some some caterpillars don't have to worry after the
first instar.
