(Linnaeus, 1771)

Fig Tree Borer

A flat-faced longhorn in the Lamiinae, notable for its variable coloration and distinctive three longitudinal bands. Males are larger than females, reaching up to 35 mm. The "Fig Tree Borer" reflects its association with Ficus .

Appearance

Body length 21–35 mm in males, 19–31 mm in females. Background coloration variable: greyish to dark brown. bear orange-brown spots and three white or yellow longitudinal bands. Body form typical of flat-faced longhorns with elongated .

Habitat

Associated with trees including fig, mulberry, willow, and alder. Specific requirements beyond host presence are not documented.

Distribution

Recorded from Belize, Rica, Cuba, Guatemala, Guyana, Honduras, Nicaragua, Suriname, United States, and Venezuela.

Diet

Larval development occurs in wood of Ficus carica, Morus microphylla, Salix sp., and Alnus sp. feeding habits are not documented.

Host Associations

  • Ficus carica - larval main plant
  • Morus microphylla - larval main plant
  • Salix sp. - larval main plant
  • Alnus sp. - larval main plant

Life Cycle

Complete with larval boring in wood. Specific developmental timing and details are not documented.

Ecological Role

Wood-boring larva in living or dead trees; contributes to nutrient cycling through wood decomposition.

Human Relevance

Potential pest of cultivated fig (Ficus carica). "Fig Tree Borer" suggests economic concern, though damage levels are not quantified in available sources.

Nomenclatural history

Originally described as Cerambyx trilineatus by Linnaeus in 1771; subsequently transferred to Neoptychodes.
