A Black Swallowtail Caterpillar discovered on one of our dill plants. This variety of butterfly likes carrot-type plants, thus including dill and parsely. For those seeking hard knowledge, this creature's Latin name is Papilio polyxenes.
Brigitte named him Aristo, based entirely on his heraldic appearance, transferred him to a pot, placed him under glass, and anticipated a genuine biological experience watching a real metamorphosis unfold. Aristo ate like champion; Brigitte fed him parsely and dill. He preferred dill but consumed the parsely too.
Another week passed. Suddenly, sometime between noon and three-thirty in the afternoon, unobserved by human eyes, Aristo escaped from its small green hull and unfolded its glorious plumage as shown here. Note the two eyes, Here's Looking at You, that no doubt make birds hesitate before disturbing this magnificence. The photograph is through the plastic container that then still held Aristo.
Here is another view. In this one the top portion of his hull is visible at the top.
We transported Aristo fifty miles to the Magee Domain on the Shores of Lake Wolverine. Here is Aristo less than a minute after his release into the wilds resting on a Black Eyed Susan.
By the way, we called him "he" without good rhyme or reason. It might have been a Lady. Aristo became a caterpillar in Grosse Pointe Farms, Michigan. As a chrysalis he travelled to Stratford, Ontario. We dared not leave him alone. Back home again, he turned butterfly—but then travelled another goodly distance before at last he was, as we say around here, "born free."
