Appearance

Monarch eggs are usually attached to the underside of young milkweed leaves. They are laid singly, and it is uncommon (though not unheard of) to find more than one on a single plant. The eggs look off-white or yellow, and are marked with a series of longitudinal ridges. The hard outer shell, or chorion, protects the developing larva.
