Behavior

Males produce a volatile , (R)-2-methylbutan-1-ol, which likely functions in mate attraction. The exhibits seasonal activity with potential for temporal overlap with , suggesting possible mechanisms for reproductive isolation such as pheromone component variation, specificity, or stratification.

Pheromone chemistry

The male-produced (R)-2-methylbutan-1-ol is part of a conserved pheromone motif found across Phymatodes , often in combination with (R)-3-hydroxyhexan-2-one.
