The genus Eucoleocerus belongs to the Curculionidae family, which is the family of true weevils, and is a part of the subfamily Entiminae. These are commonly known as broad-nosed weevils, a group that is distinguished by their relatively large and broad snouts (rostrum), which are typical of the weevil family.

Diet

  • Adults: Herbivorous, feeding on leaves and other plant tissues. Specific host plants are not well documented.

  • Larvae: Presumably develop in association with plant material, but the immature stages and feeding habits of E. conicicollis are poorly known.

Range

  • Eucoleocerus conicicollis is a Neotropical weevil known from Mexico, Guatemala, Honduras and Nicaragua.

  • In Mexico, it has been recorded in Morelos and other regions.

  • The species is also associated with the Zihuatanejo region of Guerrero, where it occurs among the tropical weevil fauna.

Habitat

  • Associated with tropical dry forest, tropical deciduous forest, woodland, forest edges and secondary vegetation.

  • Adults are likely to occur on foliage and low vegetation, particularly where suitable host plants are present.

  • The biology of the immature stages is poorly documented.

Size

  • Adult length: approximately 5–10 mm (0.2–0.4 in).

  • Body compact and robust, with the broad rostrum and stout form characteristic of Entiminae.

  • The species has a distinctly conical pronotum, reflected in the name conicicollis (“conical-necked” or “conical-pronotum”).
