I've been told that back in "old" Europe people thought the yellow jackets came from butcherd hogs.
Also been told that it is because of the yellow jacket that the German beer steins have lids. Yellow jackets are more aggresive in the fall...during October Fest.
And...I'm pretty sure that the yellow jacket is a non-native wasp brought over here from the "old world". White Man Flies.
I haven't looked @ Tracy's link, some of this may be old news.
Keep your sweet drinks covered, dpg
p.s. I watched the link...stining insects get a bad name. IMO
