About the Palm Seed Weevil

Caryobruchus gleditsiae is a species of beetle in the family Chrysomelidae (formerly Bruchidae). It lives in North and Central America and develops inside the seeds of palm trees. Adults grow to a maximum length of 11 mm (0.43 in), the size depending on the size of the seed it grew up in. The species was first described by Carl Linnaeus in his 1763 Centuria Insectorum.

Adult beetles are from 4 to 11 millimeters (0.16 to 0.43 in) long, with the body size depending on the size of the seed it grows in as a larva. It is the largest species of Bruchidae in the United States, although other species within the genus can reach 25 mm (0.98 in) long. The adults are black, with short grey hairs and scattered white spots on the elytra.

Caryobruchus gleditsiae is found in the southeastern United States, Mexico, Central America, the West Indies and the Bahamas. A closely related species, Caryobruchus mariae, is found on Cuba. Another closely related species, Caryobruchus maya, is found in southern Mexico, Belize and Guatemala.
