Egg of Nessus Sphinx. I saw an adult ovipositing on the small twin emergent leaves (cotyledons?) of Virginia Creeper, Parthenocissus quinquefolia--at least that is what I think the plant to be--there were typical five-fingered leaves nearby. The eggs were laid on the underside of the leaves. They are pale green spheres, just over 1 mm in diameter, and virtually featureless.
