Neoptychodes trilineatus is a species of longhorn beetle in the family Cerambycidae, known for its distinctive coloration and elongated body. Longhorn beetles, including those in the genus Neoptychodes, are recognized for their prominent, long antennae that can be as long as or longer than their bodies.

Diet

  • Adults: Feed on bark, leaves and tender tissues of woody plants. The species is particularly associated with fig trees (Ficus spp.), but adults can use a variety of other plants.

  • Larvae: Wood-boring, developing inside branches and trunks. Young larvae initially feed beneath the bark before tunnelling deeper into the wood.

Range

  • Neoptychodes trilineatus has a remarkably broad distribution extending from the southern United States through Mexico and Central America into northern South America and the Caribbean.

  • It is widely distributed in Mexico, including Guerrero, and is associated with tropical dry and deciduous forests.

  • Around Zihuatanejo, it is fairly common to occasional, particularly where fig trees and other suitable woody hosts are present. It is a species worth looking for on trunks and branches rather than only among flowers.

Habitat

  • Found in tropical dry forest, tropical deciduous forest, woodland, orchards, gardens, agricultural areas and urban vegetation.

  • Around Zihuatanejo, look closely at fig trees, damaged branches, dead or weakened wood and tree trunks, especially in warm sunny locations.

  • Adults may sit motionless against bark, where their mottled brown coloration provides effective camouflage.

  • The species is particularly associated with fig trees, and can develop in both cultivated and wild Ficus.

Size

  • Adult length: approximately 19–24 mm (0.75–0.95 in). A measured specimen was 24.2 mm long.

  • Body elongated and somewhat flattened, with extremely long antennae.

  • Usually greyish-brown to dark brown, with orange-brown mottling and three conspicuous pale longitudinal bands running along the elytra.

  • The three pale lines are the most useful field clue and are reflected in the species name trilineatus, meaning “three-lined.”
