Eudiagogini is a tribe of broad-nosed weevils in the family Curculionidae, subfamily Entiminae. These beetles are primarily found in the Americas, especially in tropical and subtropical regions such as Mexico and Central America, where they inhabit forests, scrublands, and agricultural areas. Like other weevils, they possess elbowed antennae that arise from the snout. Many species are flightless or weak fliers, relying instead on walking and camouflage to avoid predators.

Diet

  • Adults: Primarily herbivorous, feeding on leaves, stems, buds and other plant tissues. Many species are associated with leguminous plants, particularly members of the pea and bean family (Fabaceae).

  • Larvae: Develop in association with their host plants and feed on roots, stems or other plant tissues, depending on the species.

  • Host-plant relationships can be relatively specialized within the tribe.

Range

  • Eudiagogini is primarily a New World tribe, occurring from the southern United States through Mexico and Central America into South America.

  • The tribe is particularly diverse in tropical and subtropical regions.

  • Species occur in Mexico, including tropical areas of Guerrero and the Zihuatanejo region.

Habitat

  • Found in tropical dry forests, tropical deciduous forests, grasslands, scrubland, woodland edges, agricultural areas and secondary vegetation.

  • Adults are generally encountered on host-plant foliage, while larvae develop in or around plant tissues and roots.

  • Several species are associated with leguminous vegetation in open and disturbed habitats.

Size

  • Adult length: approximately 4–12 mm (0.16–0.47 in), depending on species.

  • Body generally compact and robust, with a broad rostrum and elbowed antennae typical of weevils.

  • Colouration ranges from brown and grey to darker or mottled forms that provide camouflage among foliage and plant debris.
