Conotelus is a genus of sap-feeding beetles in the family Nitidulidae. Sap-feeding beetles are rather small drab beetles distinguished by a very pronounced club on the tip of the antenna. The majority of sap beetles feed on fungi, but as the name suggests others are attracted to fresh tree wounds and sap flows where they feed on yeats and other fungi. Some species will also feed on pollen and act as pollinators.

Diet

  • Adults: Feed primarily on fermenting plant material, flowers, pollen, nectar, and ripe or damaged fruit. Some species are particularly associated with flowers of grasses and other plants.

  • Larvae: Feed on decaying plant material, fungi, and fermenting organic matter, often developing in plant debris or within flower structures.

  • Some species are associated with sugar-rich plant material and sap.

Range

  • The genus Conotelus is primarily Neotropical, distributed from the southern United States through Mexico, Central America, the Caribbean, and South America.

  • Mexico has several species, particularly in tropical and subtropical regions.

  • Species occur along both the Pacific and Gulf coasts, including Guerrero.

Habitat

  • Found in tropical dry forests, tropical rainforests, woodland edges, agricultural fields, orchards, gardens, and disturbed vegetation.

  • Adults are frequently associated with flowers, fermenting fruit, plant sap, and decaying vegetation.

  • Larvae develop in moist, organic-rich plant material.

Size

  • Adult length: approximately 3–7 mm (0.12–0.28 in).

  • Body elongate-oval and somewhat flattened, usually brown to black, with the compact form typical of many Nitidulidae.
