Females lay their eggs in small clusters on spurge leaves.

The caterpillars pupate in loose cocoons just below the surface of the soil.

The caterpillars are brightly colored, developing bright red or yellow stripes along their body.

The caterpillars have a prominent horn at the tip of their abdomen.

The adults, Spurge Hawk Moths, eat the nectar of flowers.

Fun fact: they were intentionally introduced to Colorado to control the leafy spurge populations.
