-Subfamily Eurygeniinae


The Eurygeniinae subfamily, commonly known as ant-like flower beetles, is a group within the family Anthicidae. These small beetles are so named due to their resemblance to ants, which helps them avoid predation. Eurygeniinae beetles are generalist feeders and are often found on flowers, where they consume pollen, nectar, and other small organic materials. They may also scavenge on decaying plant matter, small insects, or fungi.

Diet

  • Adults: Generally feed on small insects, insect eggs, pollen, nectar, fungi and decaying organic material. Feeding habits vary among genera.

  • Larvae: Often develop in dead wood, under bark, in plant debris or other decaying organic material, where they feed on small invertebrates, fungi and decomposing material.

  • Some species are associated with ant nests or other insect colonies.

Range

  • Eurygeniinae is distributed primarily in warm and temperate regions of the Americas, with representatives also occurring in other parts of the world.

  • The subfamily is well represented in Mexico, including tropical and subtropical regions of Guerrero and the Zihuatanejo area.

  • Diversity is greatest in habitats containing abundant dead wood, leaf litter and decomposing vegetation.

Habitat

  • Found in tropical dry forests, tropical rainforests, woodland, scrub, forest edges, fallen logs and areas of accumulated leaf litter.

  • Adults may occur beneath loose bark, in dead wood, among plant debris and around flowers.

  • Larvae are generally concealed in decaying wood or other protected organic material.

Size

  • Adult length: approximately 2–8 mm (0.08–0.31 in).

  • Small, generally elongate beetles with compact bodies.

  • Many species have reddish-brown to black coloration, sometimes with contrasting markings.
