Two of two dozen Giant Swallowtail larva feasted
on the new growth of an old grapefruit tree that
was kicked out of my house for the summer.
From the number of leaves consumed, I am sure they
matured and are now pupae somewhere in the backyard.
I brought home a third caterpillar a week ago
to be fed prickly-ash leaves. Resulting pupa is on Flickr:
