If you search for the brown stink bug species Euschistus rugifer in iNaturalist, you won't find much; indeed, zero observations entered in the US. Similarly, an entry on BugGuide.net has little more than a few images of a specimen and its structure. Elsewhere, it seems the species is described primarily in literature out of Latin America (ref. Artropodos de Chamela. edited by Alfonso N. García Aldrete, Barajas Ricardo Ayala, 2004). Yet it seems the range of this species may soon include the US, traveling into the country on board shipments of agricultural products. Several news accounts mention records from San Francisco (2014), Arizona and the Rio Grande Valley of Texas, but perhaps the most dramatic is the identification of insects found in a Customs seizure at Dallas-Fort Worth Regional Airport just this month, strikingly far inland for a new incursion. Information on the life history of this species (in English sources, at any rate) is also scarce, but it would seem E. rugifer has a fondness for culinary herbs. As always seems to be the case, humans in movement and the goods that accompany them are the main means of transport for this potential pest, with small teams of inspectors at points of entry being the nation's only defense.
