He seemed to be a bit dehydrated and not doing very well, so I kept him overnight then set him free.

By the time I let him go, Alfred had changed color considerably.
Mosquito
A different swallowtail catterpiller. This one was more brown and bigger than Alfred--an indication that it was all that closer to pupating. (Is that the right word?)
