What do swallowtail caterpillars look like

They mate and then the females lay small white eggs on the underside and tops of plant leaves. The eggs hatch in days. The caterpillar that emerges is black with a white band around its middle. As it grows, it develops reddish orange spikes on its body. Later, the white band disappears and the caterpillar develops green and black bands with yellow spots. It pupates for days, unless it is in the generation that overwinters. The second group of butterflies emerges in the late summer.
