Batrachedra pinicolella
Pine Cosmet
A small conifer-feeding moth in the family Batrachedridae. Formerly cryptic within a species complex, integrative taxonomic studies using DNA barcoding, nuclear markers, and ddRAD sequencing distinguished it from the newly described B. confusella. It has a boreo-montane distribution pattern and is associated primarily with Norway spruce.
Pityogenes bidentatus
Pityogenes bidentatus is a European bark beetle that colonizes Scots pine (Pinus sylvestris). The species exhibits sophisticated olfactory-mediated behaviors for host location, including attraction to aggregation pheromone components (grandisol and cis-verbenol) and active avoidance of nonhost volatiles. Its behavioral response to monoterpene odors is context-dependent: avoidance occurs during flight but not during walking, likely representing distinct sensory mechanisms for long-range host discrimination versus short-range gallery establishment.
