Can you identify this annoying, swarming bug?

Hi. Noone I’ve talked to knows what these are. The bloom in late summer and are enormous pests through sheer numbers. They crash-land on everything and march around, but otherwise exhibit no behavior. They seek cracks and shelter and crowd together to winter, I suppose. I very rarely see them mating. They are a hideous annoyance that, at peak times, make it impossible to work outside. They get into EVERYTHING. Everything you open has them inside it. They are masters are penetration.

Hi Ian,
We did some research on BugGuide, and have concluded that you are being infested by Hyaline Grass Bugs, Liorhyssus hyalinus. There is considerable information on BugGuide on how to properly identify the species, but no information on its habits. We have not had much luck locating other information except a vague reference that they are pests on Sorghum. We would question if perhaps there are Sorghum fields near your residence.

Hi Daniel…
That certainly looks to be it!  Thanks so much.  I will find out if sorghum is grown around here.  I’m in the middle of acres of “buck brush” in scrub country, no crops are grown within a couple miles at
least.  Hmm…  I read up some and it said they eat sorghum and pistachio fruit– two very different things– which makes me wonder if there are others things it eats, something very common around here. Anyway, thanks again for the ID, that really helps.  If you like, I
can send you a few trillion for your collection.

Thanks for the offer Ian, but our entire collection of bugs is online.
