Leptoglossus
leaf-footed bugs
Leptoglossus is a genus of true bugs in the leaf-footed bug family Coreidae, tribe Anisoscelini. Species are characterized by leaflike dilations of the hind tibia, a diagnostic trait of the genus. The genus is distributed throughout the Americas, with some introduced populations in Europe and Asia. Several species are economically significant agricultural pests, notably L. occidentalis, which has become invasive in multiple continents.

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.
