(Say, 1831)
Agraphus bellicus is a of broad-nosed in the , first described by Thomas Say in 1831. It belongs to the Entiminae, a diverse group of weevils characterized by their elongated snouts and root-feeding . The species has been documented in several eastern U.S. states, with records concentrated in the Mid-Atlantic and Florida regions. Like other members of its , it is likely associated with , though specific ecological details remain poorly documented.

Appearance
As a member of , possesses the -defining elongated with at the tip. Typical of Entiminae, has a broad, rounded body form with relatively short, clubbed that insert near the middle of the rostrum. Specific coloration and size details for this are not well documented in available sources.
Habitat
Recorded from coastal and near-coastal environments in the eastern United States, including sandy areas in New Jersey and Florida. Specific microhabitat preferences are not documented, though are often found in association with herbaceous plants in open, disturbed, or early successional .
Distribution
Eastern United States: documented from Florida, New Jersey, New York, North Carolina, and Pennsylvania. Distribution appears concentrated in the Mid-Atlantic coastal region with disjunct records in Florida.
Similar Taxa

Taxonomic history
Originally described as Peritelus bellicus by Thomas Say in 1831, later transferred to Agraphus. The Agraphus currently contains approximately 15 , primarily distributed in North America.
Data limitations
Despite being described nearly two centuries ago, this remains poorly known biologically. Available records derive primarily from museum specimens and scattered citizen science observations rather than systematic study.
