More precisely, females grow slightly larger than males. Overall, however, a maximum wingspan for the females equals roughly 6 in (15 cm). It’s also relatively bulky, in terms of mass. In point of fact, it ranks as the heaviest variety of moth in its part of the world.
Its great beauty nevertheless merits a degree of appreciation at least equal to its size. The forewings of the invertebrate typically present as either a gray or gray-green in color. These beautiful, but delicate, structures further display a row of small, bright yellow spots.

Regal Moth Distribution, Habitat, and Ecology
Most unfortunately, Nature limited the presence of the breathtaking Regal Moth in the world. The moth evolved as natural to a moderately limited section of the globe. More precisely, the insect only appears natively in a comparatively small portion of North America.
That’s due to the fact that it appears naturally only in a specific portion of the United States. It further lives only in the eastern sections of the country. That range extends from New Jersey to Missouri, to eastern Texas and central Florida, and all points east of those.
Even within that range, though, its population remains somewhat clumped. The lovely insect currently remains more common in the southern sections of this range. The precise reason for this tendency, however, currently remains undetermined by researchers.
The Regal Moth also displays a decided preference regarding its precise habitat. While it will stay in a restricted variety of tree species if its preferred choices remain unavailable, it greatly prefers walnut and hickory trees. This also leads to the term for its larval form.
After mating, the females spend most of the rest of their lives laying eggs. The male, meanwhile, frequently mates several more times before he dies. Like other moths, it evolved as a nocturnal species. Bats form its leading predator, along with certain types of flies.
