The Waved Sphinx (scientific name: Ceratomia undulosa) is a fascinating type of moth that belongs to the Sphingidae family, often called sphinx moths or hawk-moths. This moth got its scientific name from Francis Walker, who first described it in 1856. Sometimes, people also call it the "Scorpion Moth" because of an interesting story we'll learn about later!

Where the Waved Sphinx Lives

You can find the Waved Sphinx moth across many parts of the United States and southern Canada. They live mainly in areas east of the impressive Rocky Mountains. These moths are quite shy during the day. They are strictly nocturnal, which means they are only active at night. As the sun starts to rise, they find a safe spot to hide until darkness returns.

What Does It Look Like?

The Waved Sphinx moth is a medium to large-sized moth. Its wings often have beautiful wavy patterns, which is how it got its common name, "Waved Sphinx." The colors are usually a mix of grays, browns, and sometimes hints of white, helping them blend in with tree bark at night.

Life Cycle and What They Eat

The life of a Waved Sphinx moth starts as an egg, which hatches into a larva, also known as a caterpillar. These caterpillars are quite hungry! They love to munch on the leaves of several different trees and plants. Some of their favorite foods include:

Once a caterpillar has eaten enough and grown big, it's time for its next big change. It digs its way underground to become a pupa. This is a resting stage where the caterpillar transforms into an adult moth. After some time, the adult moth emerges from the ground, ready to fly and continue the life cycle.

The "Scorpion Moth" Mystery

You might remember that the Waved Sphinx is sometimes called the "Scorpion Moth." This nickname comes from an interesting natural interaction. A type of scorpion, the Guiana Striped Scorpion, is known to eat the eggs that the Waved Sphinx moth lays. Because these scorpions are often found near where the moths lay their eggs, some people mistakenly thought that the moths were somehow giving birth to scorpions! Of course, this isn't true; moths lay eggs, and scorpions are a completely different type of animal. The scorpions are simply predators that enjoy a meal of moth eggs.

Different Types of Waved Sphinx Moths

Within the Waved Sphinx species, there are a couple of recognized types, called subspecies. These are slightly different versions of the moth that live in various regions:

  • Ceratomia undulosa undulosa: This type is found across a wide area. It lives from eastern Canada (like Prince Edward Island and Nova Scotia) all the way west to eastern Alberta. In the United States, it ranges from Maine down to Florida, and west to the eastern Great Plains and the Gulf Coast, including Texas.
  • Ceratomia undulosa polingi: This subspecies is found further south, specifically in Mexico.
