The Eurhinus aeruginosus is a striking species of flower weevil within the family Curculionidae. Known for its vibrant coloration, this weevil is often found on or near flowers and feeds on plant material. Its iridescent appearance and unique structure make it a fascinating species among weevils. Eurhinus aeruginosus is known for its metallic, iridescent green or blue-green color, with a reflective, almost jewel-like appearance. The adult Eurhinus aeruginosus feeds on flowers, pollen, and sometimes plant leaves. Its diet mainly consists of the softer parts of plants.

Diet

  • Adults: Primarily herbivorous, feeding on leaves, buds, flowers and other tender plant tissues.

  • Larvae: The immature stages are poorly documented, but development is associated with plant material.

  • The biology of E. aeruginosus is not well known.

Range

  • Eurhinus aeruginosus is a Neotropical weevil associated with tropical regions of Mexico and Central America.

  • It occurs in Guerrero, including the Zihuatanejo region.

  • The genus Eurhinus is restricted to the Neotropics, with species occurring primarily in tropical America.

Habitat

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

  • Adults are found on living vegetation, where their metallic coloration can make them conspicuous in sunlight.

  • The immature habitat and host plant of E. aeruginosus are not well documented.

Size

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

  • Body compact and robust, with a prominent rostrum and elbowed antennae characteristic of weevils.

  • Members of Eurhinus are often brilliantly metallic, displaying combinations of green, blue, purple, bronze and red.
