The larva stopped feeding the afternoon of 09/20, remaining still through the next morning. Then the color changed from green to a metallic sea green at which point the larva began actively searching for a place to pupate.

This particular larva ended up being the largest of the dozen reared to pupation and as such probably represents a female. The smallest measured 100mm at pupation. As far as the amount of time spent feeding the group maintained on American Sweetgum (Liquidambar styraciflua) pupated the fastest. The group provided American Sycamore (Platanus occidentalis) required an average of four days longer and the group feeding on on Common Buttonbush (Cephalanthus occidentalis) took over ten days more to complete their time as larvae.
