wingspan of your thumb...thats not very big, ive ones with wingspan like (tip of one wing to the other) the size of my palm. + to whoever was writing about the hornets and bees and that i thought wasps and hornets were the same thing, just hornets was a much cooler name, like i thought americans called them hornets and we called them wasps or something, so whats the difference? wasps are the smaller yellow and black striped ones, that fly around, americans call them hornets, hornets (or wasps to the americans) are the big ones with the big long stinger(almost like an extension of their abdomen from what I remember), that can sting really fast, and a lot.
