6 Fun Facts About The White-Lined Sphinx Moth

This is the most common of the ‘hummingbird moths’.  These moths all have a large body and smaller wings, which means they need to beat their wings fast to fly.  They resemble hummingbirds when they fly and because they are able to hover in mid-air.

It is most often seen in the later afternoon and around sunset as it gathers nectar from wildflowers, such as Columbine or Larkspur.  The adults most commonly fly at dusk, during the night, and at dawn, but they can be seen during the day.

The larva or caterpillar stage of the adult white-lined sphinx moth.

This white-lined sphinx moth undergoes complete metamorphosis, changing from a caterpillar to the adult moth.  The larva or caterpillar, called a hornworm, can grow up to 3 inches long.  The caterpillars are green with pointed horns near the back.

The adult has a very long proboscis, which is what moths and butterflies use to sip nectar out of flowers.

These moths can be found throughout most of North America, from southern Canada down to Central America.  During winter they migrate south to warmer areas and then they return north in the spring.

The caterpillars bury themselves 1-4 inches in the ground when they are ready to pupate and become an adult moth.  Then just before the adult emerges, the pupae squirms up to the surface so the new moth can emerge.
