Recorded from North America, Oceania, and Southern Asia. GBIF distribution records indicate presence in these regions, though specific associations within these ranges are not documented in available sources.
Host Associations
- Lentinula edodes - pestMajor insect pest of cultivated shiitake mushroom; laboratory studies demonstrate attraction to odors from all growing stages (growing, mature, decaying) as well as re-hydrated mushrooms
Behavior
Both male and female beetles exhibit chemotactic behavioral responses to odor from all growing stages of shiitake mushroom (growing, mature, and decaying) as well as to re-hydrated mushrooms. Attraction rates vary among individual mushrooms within the same stage but are not correlated with mushroom quantity.
Ecological Role
Major insect pest of cultivated shiitake mushroom production.
Human Relevance
Documented pest of shiitake mushroom , with potential economic impact on commercial mushroom production.
