It was named after the American entomologist Henry Guernsey Hubbard, who discovered the insect in the United States.

[5][6] Originally a tropical and subtropical species in Central and South America, Usazoros hubbardi has expanded its range northwards into the United States.

Hubbard's angel insect has been detected in Alabama, Arkansas, Delaware, District of Columbia, Florida, Georgia, Illinois, Indiana, Iowa, Kansas, Kentucky, Louisiana, Maryland, Mississippi, Missouri, North Carolina, Ohio, Oklahoma, Pennsylvania, South Carolina, Tennessee, Texas, Virginia and West Virginia.

[5] Hubbard's angel insects are gregarious and are usually found under bark in small groups.

They feed on fungal spores and hyphae, and scavenge for dead mites, nematodes and other small invertebrates.

During courtship, the males offer the females droplets of a liquid secreted by glands on their heads.
