Waved Sphinx (Ceratomia undulosa) lives in eastern deciduous forests across United States and southern Canada.
Fascinating facts about the Waved Sphinx
- In 1856 Francis Walker gave science its first glimpse of the waved sphinx, a moth that would later earn the nickname "Scorpion Moth." The moniker stems from a mistaken belief that the moth actually births scorpions, because the Guiana Striped Scorpion often hangs around the same egg-laying sites. This myth highlights how close ecological interactions can spark folklore, reminding us that observing who shares a habitat can reveal surprising, sometimes misleading, stories about nature.
- The waved sphinx lives east of the Rocky Mountains, stretching from the United States into southern Canada. Its range includes everything from Prince Edward Island and Nova Scotia west to eastern Alberta, then down through Maine to Florida, the eastern Great Plains, the Gulf Coast and Texas.
- Adult waved sphinx moths are strictly nocturnal, taking to the night sky until the first light of dawn forces them into hiding. This behavior was noted in a 2001 study by Fullard and Napoleone, which linked night-time flight patterns to the evolution of auditory defenses in large moths.
- The Guiana Striped Scorpion is the waved sphinx's most common predator, feasting on the moth's egg clusters. Because the scorpion often appears right where the moth lays eggs, early observers mistakenly thought the moth gave birth to scorpions, coining the name "Scorpion Moth."
- Caterpillars of the waved sphinx munch on a surprisingly diverse menu: ash, privet, oak, hawthorn and fringe tree. When they finish feeding, the larvae dig underground to pupate.

About the Waved Sphinx
In the warm, golden light of dusk, the Waved Sphinx moth unfurls its delicate wings, a masterful blend of mottled browns and tans that echo the rustic hues of its woodland habitat. As it takes to the air, its undulating flight path weaves a hypnotic spell, the curved edges of its wings beating in a slow, sensual rhythm that belies the urgency of its nocturnal quest for nectar. With each languid stroke, the Waved Sphinx navigates the shadows, a phantom of the forest, its very existence a testament to the beauty and mystery that still lingers in the unexplored recesses of our natural world.
