Agaeocera gigas is found in tropical regions of the Americas, including Mexico, where it inhabits forests and wooded areas. Adults are often associated with sunlit vegetation, where they may feed on plant material such as leaves or possibly visit flowers. Their metallic coloration may help with camouflage among reflective foliage or act as a form of predator deterrence. The larvae, like those of other jewel beetles, are wood-borers or stem-borers, living within plant tissues where they feed and develop. These larvae are typically flattened and pale, adapted for tunneling inside wood or stems.

Diet

  • Larvae: Feed beneath the bark and within the wood of dead, dying, or weakened hardwood trees, tunnelling through the cambium and outer sapwood.

  • Adults: Feed primarily on pollen and nectar, commonly visiting flowering shrubs and wildflowers. They may also feed occasionally on tree sap.

Range

  • Native to Mexico and Central America.

  • In Mexico, it occurs in warm regions, including the Pacific coast of Guerrero and the Zihuatanejo region.

  • Its range extends south into Central America, where it inhabits tropical forests.

Habitat

  • Inhabits tropical dry forests, tropical semi-deciduous forests, woodland edges, secondary forests, and flowering clearings.

  • Larvae develop in dead or weakened hardwood branches and trunks.

  • Adults are most often encountered on sunlit flowers, fallen logs, and exposed tree trunks during warm weather.

Size

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

  • Body robust, elongated, and wedge-shaped with a hard, metallic exoskeleton.
