Summary

Bothriospilini is a tribe of beetles in the subfamily Cerambycinae with a neotropical distribution. Knulliana cincta, a notable species within the tribe, is known for its larvae that bore into hickory and oak trees, causing damage. This tribe includes several genera and species, predominantly located in the New World, and exhibits specific morphological characteristics and pheromonal communication.

Physical Characteristics

Knulliana cincta is about 15–30 mm in length and has a wide last abdominal segment that is braided in the female. It features noticeable sexual dimorphism with variations in size and shape between genders.

Identification Tips

Knulliana cincta can be identified by its size, body shape, and the presence of sexual dimorphism. It may also produce a squeaking sound when roughly handled.

Habitat

Knulliana cincta is primarily found on hickory trees and oak trees, where it lays eggs.

Distribution

The tribe Bothriospilini has a primarily neotropical distribution with approximately 4 species in the US and greater representation in the New World, particularly in South America.

Diet

Larvae bore into trees, causing potential damage, while adult dietary habits are not clearly stated.

Life Cycle

The life cycle specifics are not detailed, but it includes egg laying on suitable host trees, with larvae development occurring within the wood.

Reproduction

Reproduction involves laying eggs on host trees, after which larvae burrow into the wood.

Ecosystem Role

Bothriospilini beetles, particularly Knulliana cincta as larvae, play a role in wood decomposition as they bore into trees, which may affect tree health.

Economic Impact

Knulliana cincta can cause significant damage to hickory and oak trees due to larval boring, which may have economic implications for forestry and lumber industries.

Collecting Methods

• Visual search on host trees
• Photographic capture for observation

Preservation Methods

• Drying specimens
• Pinning with entomological pins

Evolution

The tribe was proposed by Frederico Lane in 1950, originating from the subfamily Bothriospilinae.

Similar Taxa

• Torneutini

Misconceptions

Some may believe that beetles of this tribe are harmless, but larvae can inflict severe damage on host trees.
