The polydamas swallowtail butterfly came back to lay more eggs on our Dutchman Pipe. They lay anywhere between 10-14 eggs, which are laid on new leaves, and vines.

The young caterpillars have been said to be very social and hang out together eating, feeding and molting. As they grow older they tend to go their own way.

I have found that the caterpillars will eat the petiole of the leaf, making the rest of it fall to the ground before completely eaten.
