The eastern black swallowtail caterpillars are changing and growing and its so fascinating to watch.

This eastern black swallowtail has been called the parsley caterpillar, and has been known as a nuisance, as it feeds on parsley and dill. They can feed on dill in my garden, no problem.

These caterpillars also have their little horns, which they have already displayed. It’s called osmeteria and is located at the back of its head. When extended it lets out an awful odor into the air, which I have yet to smell.

Interesting fact: swallowtail butterflies often have black wings, as they absorb more heat, warming the butterflies.

Did you know there are around 560 species of swallowtail butterflies worldwide with 10 species residing in Florida, the most in one state in the United States?
