Rhopalophora is a genus of longhorn beetle in the family Cerambycidae. Long, segmented antennae that are typically longer than the body in males and can be approximately equal to or shorter than the body in females. The antennae are a distinguishing feature of longhorn beetles and help with sensory functions, such as detecting chemical cues.

Diet

  • Adults: Primarily feed on pollen, nectar, flowers, sap and tender plant tissues. Adults are often associated with flowering plants and woody vegetation.

  • Larvae: Wood-boring, developing inside dead, dying or weakened branches and stems, where they tunnel through the wood.

  • The specific host plants vary among Rhopalophora species, and some are associated with particular tree or shrub species.

Range

  • Rhopalophora is a New World genus of longhorn beetles in the family Cerambycidae, subfamily Cerambycinae.

  • Species occur from the United States through Mexico, Central America and into South America, with Mexico supporting a particularly diverse fauna.

  • Around Zihuatanejo, Rhopalophora is occasional. The tropical dry forest provides suitable habitat, particularly where flowering vegetation and dead or weakened branches are present.

Habitat

  • Found in tropical dry forest, tropical deciduous forest, woodland, scrub, forest edges, orchards and secondary vegetation.

  • Adults may be encountered on flowers, foliage, tree trunks and branches, especially during warm weather.

  • Dead and recently fallen branches are important habitat for the developing larvae.

  • Around Zihuatanejo, checking flowering trees and shrubs during the day, followed by examination of dead woody material, can increase the likelihood of finding Rhopalophora.

Size

  • Adult length: approximately 8–25 mm (0.3–1.0 in), depending on species.

  • Body elongate and generally cylindrical, with long antennae characteristic of longhorn beetles.

  • Many species have attractive reddish, orange, yellow, brown or black colouration, sometimes with contrasting bands or spots.

  • The pronotum is often distinctly shaped and may be narrower than the elytra.
