Don’t you love the colors of the third stage, or instar, of the Cecropia Moth caterpillar? Only about an inch and a half long in the photo, in the final fifth instar, before it pupates into a cocoon, the caterpillar will be as large as a large man’s thumb.

This is an evolutionary form of mimicry against predation by birds. Cecropia Moth caterpillars eat not only the foliage of American White Birch trees, but also other species of birch trees, apple, ash, beech, elm, lilac, maple, poplar, Prunus and Ribes species, white oak, and willow.

Thank you so much again to my friend Christine for the gift of the Cecropia moth eggs.
