Yellow jacket - is this a queen? - Vespula germanica
Winona, Winona County, Minnesota, USA November 12, 2010 Size: .75 inch long
Found this in our bathroom today; I believe it got in through our bathroom fan. We have been dealing with a yellow jacket problem for the last several weeks, and since this one has a different appearance from the others we have seen, I'm wondering if it is the queen.
