-Genus Colecerus


The Colecerus genus, part of the Curculionidae family, consists of broad-nosed weevils known for their distinctive, robust snouts and relatively wide heads. These weevils are plant feeders. Colecerus larvae may feed on the roots or lower stems of plants, depending on the species and habitat.

Diet

  • Larvae: Feed within the wood and inner tissues of dead, dying, or weakened trees and shrubs, creating tunnels through the bark, cambium, and sapwood.

  • Adults: Feed primarily on pollen, nectar, flowers, tree sap, and tender plant tissues, although feeding varies among species and may be limited.

Range

  • Colecerus is a Neotropical genus of longhorn beetles distributed from Mexico through Central America and into northern and tropical South America.

  • Several species occur in Mexico, including tropical regions of the Pacific slope and Guerrero.

  • Greatest diversity occurs in tropical forests.

Habitat

  • Found in tropical dry forests, tropical rainforests, woodland edges, secondary forests, forest clearings, and disturbed wooded habitats.

  • Larvae develop inside dead branches, fallen logs, stumps, and weakened woody stems.

  • Adults are commonly found on tree trunks, branches, foliage, and flowers.

Size

  • Adult length: approximately 10–25 mm (0.4–1.0 in), depending on species.

  • Body elongated and cylindrical, with long antennae characteristic of Cerambycidae.
