Leptoglossus occidentalis

A new one to me: I discover that it was first introduced into Europe, probably in a load of timber shipped from USA to Italy, in 1999.
Wikipedia has a good article on the species: noting that they are "sometimes mistakenly identified as Stink bugs due to the unpleasant aroma they emit when disturbed."
The article also notes "it is not monophagous... though it seems to prefer resiniferous plants... rich in terpenes... produced by plants to deter herbivores, it might be that in evolving its ability to overcome these defenses, L. occidentalis actually became somewhat dependent on such compounds."
