Lepidoptera
- At first glance, the monarch butterfly seems built for beauty, not endurance. Its paper-thin wings look like they could tear in a strong breeze, and its delicate body appears better suited for floating between flowers than crossing continents. Yet these seemingly fragile creatures pull off one of nature's most incredible feats: a 3,000-mile migration. Just like geese, caribou, and senior citizens, they undertake this migration to avoid the harsh winters of the north.

The genus includes species commonly known as 'desert marigolds,' a name shared with an unrelated plant genus of the same name. The moths are found in North America, particularly in arid and semi-arid regions of the southwestern United States and northern Mexico. The genus name creates potential for confusion with Baileya (Asteraceae), a genus of desert wildflowers.
Baileya dormitans
Sleeping Baileya Moth, Sleeping Baileya
Baileya dormitans, commonly known as the sleeping baileya or sleeping baileya moth, is a species of nolid moth in the family Nolidae. First described by Achille Guenée in 1852, this species occurs in North America. The specific epithet 'dormitans' refers to a sleeping or dormant state, reflected in its common name.
