wasps and hornets are very cool too.
they are both great in the garden for catching bugs and aphids and the like. Wasps only look for sweet things in the end of the summer as the midges etc die, trying to make sure queeny gets fed to hibernate for the winter. They do have the worst sting though, and are the more aggressive at the end of the summer.
Hornets are fab and build great nests (DIY designs can be found on google), also eating a lot of flying pests in gardens. yes they are mahooosive, but their sting is very similar to that of a bee in make up as it is made to deter mammals who break in to their nests as they too make honey.
