Brown marmorated stink bugs

7181.    Hi, I was just wondering… Are these stink bugs doing what I think they’re doing? Are they propagating the species? Pelham, Alabama United States

Number 7181.  If you mean mating, yes they are. Also, they are brown marmorated stink bugs, Halyomorpha halys (Hemiptera/Heteroptera: Pentatomidae). This is an introduced species that has become a pest, primarily in orchards, in many areas of North America. They will come indoors in search for shelter, but do no harm there.
