CATERPILLAR OF THE WEEK: A comical face hidden among the leaves, the spicebush swallowtail caterpillar, Papilio troilus, is one of the region's most striking and well-developed predator mimics.
I still remember the first time I discovered one of these charismatic caterpillars in the wild. It was like opening up a present. A folded green leaf shelter is not an uncommon site on a sassafras or spicebush plant, but not every one holds a teary eyed, bubbly clown. It is impossible not to assign this caterpillar's decorated thorax all the personality of a puppy.
Strange to think that the eyes and expression that make this caterpillar so personable to us, evolved to strike terror and caution into hunting warblers and wrens.

"Caterpillar of the Week" will highlight a different species we grow in The Caterpillar Lab each week… or, you know, at least SOME weeks. We hope you enjoy meeting the caterpillars of New England!
