[1] Caryobruchus gleditsiae is found in the southeastern United States, Mexico, Central America, the West Indies and the Bahamas.

[2] Another closely related species, Caryobruchus maya, is found in southern Mexico, Belize and Guatemala.

[1] Eggs are only laid on a seed if it has had the exocarp and mesocarp removed, probably by rodents, revealing the smooth endocarp (see fruit anatomy).

[6] Recorded host plants for C. gleditsiae encompass a variety of Sabal species (including S. bermuda, S. causiarum, S. domingensis, S. etonia, S. glabra, S. longipedunculata, S. mexicana, S. minor, S. palmetto, S. parviflora, S. rosei, S. uresana and S. yapa) as well as other palm species, such as Coccothrinax argentata, Copernicia sp., Phoenix sylvestris, Livistona chinensis, Roystonea sp., Thrinax microcarpa and Washingtonia filifera.

[2] The holotype has since been lost, and no neotype was designated when the species was re-described by Jan A. Nilsson & Clarence Dan Johnson in 1990.
