Summary

Acanthocinus pusillus is a species of longhorn beetles first described in 1837, known for its long antennae and boreal distribution across North America. It primarily inhabits coniferous forest areas and plays an important role in wood decomposition.

Physical Characteristics

7‒13 mm in length, characteristic long antennae typical of longhorn beetles.

Identification Tips

Look for the elongated body shape and long antennae, which can be up to 3 times the body length.

Habitat

Commonly found in boreal forests, particularly associated with coniferous trees.

Distribution

Boreal transcontinental distribution; found from Alaska to Newfoundland, and south to British Columbia, Montana, Ohio, and North Carolina.

Diet

Larvae feed on the wood of coniferous trees.

Life Cycle

Undergoes complete metamorphosis with egg, larval, pupal, and adult stages.

Ecosystem Role

Plays a role in the decomposition of wood and nutrient cycling within forest ecosystems as a wood-boring beetle.

Economic Impact

Potential pest in forestry due to larvae feeding on wood, affecting tree health.

Collecting Methods

Traps baited with attractants
Hand collecting from host trees

Preservation Methods

Pinned specimens
Alcohol preservation for larvae
