Deltaspis rubriventris is a species of longhorn beetle belonging to the family Cerambycidae. It is characterized by its elongated body and distinctive coloration, typically featuring a reddish or orange-red abdomen that contrasts with darker, often metallic or black elytra (wing covers). Like other members of its genus, Deltaspis rubriventris has long antennae, often as long as or longer than its body, which it uses for sensory perception.

Diet

  • Larvae: Feed within dead, dying, or weakened branches and stems of woody plants, tunnelling through the wood as they develop.

  • Adults: Feed on pollen, nectar, sap, flowers, and tender plant tissues, although adult feeding habits are not well documented for this species.

Range

  • Deltaspis rubriventris is a Neotropical longhorn beetle in the family Cerambycidae, subfamily Cerambycinae, tribe Trachyderini.

  • The genus is centred in Mexico and Central America, with D. rubriventris associated with tropical regions of Mexico.

  • Mexican records include the Pacific slope, making it relevant to the beetle fauna of Guerrero.

Habitat

  • Found in tropical dry forests, tropical deciduous forests, woodland edges, secondary forests, and forest clearings.

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

  • Adults may be encountered on tree trunks, branches, foliage, and flowers, particularly in warm, sunny conditions.

Size

  • Adult length: approximately 15–25 mm (0.6–1.0 in).

  • Body robust and elongate, with the long antennae characteristic of Cerambycidae.
