Yeah the suits they wore were specially made to resist the stings which can defeat the usual bee outfits quite easily, they have a quarter inch long stinger and can sting multiple times.
One thing I don't get and have not seen any mention of it, is why they nested in a tree 8' off the ground? Apparently they are usually a ground nesting bug, using holes often left by small critters and rodents etc., at least in Asia.
I thought maybe climate but I don't think there is much difference between the climate in western WA and the Pacific coastal regions of Asia, both are fairly moderate, often wet climates.
Played rookie league for the Yankees in Paintsville after winning the College World Series at Fullerton State, in1979. All I could think about was the movie “Deliverance”- lived up in a hollow with some other players. Refused to go on a moonshine run because it was a dry county-no way. Met some of the nicest people on the planet there! Van Lear the home of Loretta Lynn was highlight of summer LOL.
Mule deer and Colorado elk seasons almost done! Hunters driving farm roads, looking for racks, their PH driving them along, I ask that you not pull into my drive. The buck behind me, on the boundary line of the GMU somehow knows. The hunter laughs, I would invite you in to see my Searcy rifles but social distancing prevails, darkness arrives and the buck slides away into secret tree grove...
