Below you can see that the individual above excreted all remaining waste. The droppings from Papilio canadensis caterpillars are always very dry until this final excretion.Below is the chrysalis of the individual which had turned brown two days ago. It is incredibly cryptic. It looks just like a broken branch.
Here are some photos showing the pre-pupation and chrysalis of Papilio canadensis. These photos were taken today. The hanging individual below and the chrysalis are 2 different individuals.
