Tytthonyx is a genus of soldier beetles in the family Cantharidae. These beetles are usually found in warm, temperate to tropical regions and, like many cantharids, are thought to play ecological roles as both pollinators and predators. Adults are often seen on flowers, where they feed on nectar and pollen, while their larvae are likely ground-dwelling predators of small invertebrates.

Diet

  • Adults: Primarily predatory, feeding on small insects, aphids, mites and other soft-bodied arthropods. Some adults may also visit flowers for nectar and pollen.

  • Larvae: Predatory, living in leaf litter, soil, decaying vegetation and beneath bark, where they hunt small invertebrates.

  • Their predatory habits make them useful members of the insect community, particularly where small herbivorous insects are abundant.

Range

  • Tytthonyxini is a tribe of soldier beetles (Cantharidae) occurring primarily in the New World, with its greatest diversity in tropical and subtropical regions.

  • The tribe occurs in Guerrero, and suitable habitat is present around Zihuatanejo.

  • It is occasionally sighted in Zihua, particularly during the rainy season, when flowering vegetation and small insect prey become abundant.

Habitat

  • Found in tropical dry forest, tropical deciduous forest, woodland, scrub, forest edges and secondary vegetation.

  • Adults are often found on flowers, foliage and grasses, where they hunt small insects or feed on nectar and pollen.

  • Around Zihua, check flowering shrubs and trees, low vegetation and vegetation along forest edges, especially during humid weather.

  • Larvae are more difficult to find and occur in leaf litter, soil and decomposing organic material.

Size

  • Adult length: approximately 4–12 mm (0.16–0.47 in), depending on species.

  • Body generally elongate and soft-bodied, with relatively long legs and antennae.

  • Colouration commonly includes combinations of black, brown, yellow, orange or reddish markings.

  • Some species have contrasting patterns that can make them superficially resemble other chemically protected insects.
