Hey — wanna see a talk that combines the following. Black swallowtail butterflies, William Harvey, snarky robotic aliens from Alpha Centauri, and more.
What amazes me is how the female butterflies can smell dill over great distances, and so deposit their eggs on the right plants.
The dill and parsley plants in our box garden are loaded with black swallowtail caterpillars.
Somehow this handsome fellow found his way into my office.
