This afternoon I counted 51 polydamus swallowtail caterpillars among our three Dutchman pipe plants. They are all still small with the majority in clusters, with only a few going out on their own searching for new leaves. Thank goodness we have plenty of food for them because there are more clusters of eggs.
I found so many baby polydamas caterpillars in the garden this morning. Just briefly scanning the Dutchman pipe, I found four different clusters of caterpillars, which at this stage of its instar is incredibly common. They explore on their own when they get larger.
I now have three different Dutchman pipe plants thriving in the garden, all vining up an archway and across a rope meeting together. The abundance of large green leaves, I am sure will soon disappear as the caterpillars continue to grow.
Be sure to check my polydamas butterfly page for more information about the life cycle, which of course shows many photos from our gardens:

The polydamas swallowtail has been busy laying clusters of eggs on our Dutchman pipe: one of two I found just today. The eggs are about 1 mm in diameter and will look greenish as they mature, ready to hatch, which takes up to six days. According to the University of Florida, the eggs are covered by a “hard, nutritious secretion,” which are laid in vertical bands.
The larger polydamas caterpillars in our butterfly house have been crawling around finding the perfect place to make its chrysalis. This one did not like me getting close, as its osmeterium shot out when I neared. According to the University of Florida, the osmeteria, located on the anterior of the prothorax, is bright orange, and used as defense.
