One must really keep the eyes peeled and rolling in a fine frenzy. Look out! Down on the sidewalk, a little under 1.5″ long, easily mistaken for a turd or cigarillo butt. But, actually, it’s the larva of the Eastern Tiger Swallowtail (Papilio glaucus), that gloriously large yellow and black butterfly. Early instars, or stages, of this caterpillar look like bird droppings (that old camouflage trick!); middle ones are vivid lime green, with the false eye spots; the last before pupation will look like this. Tuliptree, magnolia, and black cherry are among the food plants for this species; this was next to a Tuliptree (Liriodendron tulipifera), which is an unusual street tree here. Like all caterpillars, it is a machine for eating, powering up for the biochemical alchemy of metamorphosis. Shazam! I mean, shit into gold, the alchemical dream right here.
