The Euphoria biguttata is a beetle species belonging to the family Scarabaeidae (scarab beetles) and the subfamily Cetoniinae (flower chafers). Members of the genus Euphoria are known for their colorful, often metallic appearances and their association with flowers and decaying organic material. Adults: Primarily feed on nectar, pollen, and fruits. Often found on flowers, where they may consume floral parts. Larvae: Feed on decaying organic matter, including plant debris and rotting wood.

Diet

  • Adults: Feed primarily on sap, ripe and fermenting fruit, flowers, nectar and pollen. They may also visit tree wounds and sap flows.

  • Larvae: Develop in decaying organic matter, including rotting vegetation, compost, manure and other decomposing plant material.

  • Adults are particularly attracted to fermenting fruit and sap, which can make them conspicuous around fruiting trees.

Range

  • Euphoria biguttata is a North and Central American flower chafer, ranging from the southern United States through Mexico and into Central America.

  • It occurs in Mexico, including warm regions of western and southern Mexico.

  • The species can occur in the broader Guerrero region, including habitats around Zihuatanejo where suitable fruiting and flowering vegetation is present.

Habitat

  • Found in tropical dry forest, tropical deciduous forest, woodland, scrub, orchards, gardens, agricultural areas and forest edges.

  • Adults are frequently found on flowers, fruit, sap flows and tree trunks.

  • Larvae occur in soil and decomposing organic material, particularly around fallen vegetation and accumulated plant debris.

Size

  • Adult length: approximately 12–18 mm (0.47–0.71 in).

  • Body robust, oval and strongly convex, with the characteristic lamellicorn antennae of scarab beetles.

  • Adults are generally dark brown to blackish, with contrasting pale or yellowish markings on the elytra.
