Summary
Xyleborus is a genus of bark beetles that infests woody plants, with significant diversity globally and a notable role in forest ecosystems.
Physical Characteristics
Small to medium-sized beetles with a cylindrical body shape, typically dark brown to black in coloration. They have a distinctive rostrate (elongated) head and reduced wings in some species.
Identification Tips
Look for the small size and shape characteristic of bark beetles; some males are flightless. Examining the gallery structure and the species of host plants can also provide identification clues.
Habitat
Primarily found in wooded areas where they infest various woody plants, often associated with bark.
Distribution
Over 500 species worldwide, with several species occurring in the eastern regions of the study area; 16 species identified in the local area, with 3 adventive species from Eurasia.
Diet
Primary diets consist of the wood and phloem of their host trees, which they feed on as larvae and adults.
Life Cycle
The life cycle includes egg, larval, pupal, and adult stages. Some species exhibit parthenogenesis in reproduction.
Reproduction
Reproduction occurs through mating within the brood galleries; males are typically haploid and may mate with females that are siblings or parents.
Ecosystem Role
As decomposers and pest organisms, they influence forest health and tree populations. They may also play a role in the life cycles of various fungi.
Economic Impact
Can have significant effects on timber industries due to their ability to weaken or kill trees, leading to economic losses.
Collecting Methods
- light traps
- hand collection from infested wood
- bark examination
Preservation Methods
- alcohol preservation
- drying and pinning specimens
- freezing for a short term
Evolution
Part of the subfamily Scolytinae, with evolution marked by adaptations to specific host plants and environmental conditions.

Misconceptions
Often confused with other species of bark beetles; ecological roles may not be fully understood by the public, leading to misconceptions about their impact on trees.
