Photographing certain apiarian plants I observed an insect that I do not have look again. He was too much competitive with the bees but also with the rests of his species. Above in the tree it would be roughly 40 from them. It resembles with very with wasp, but flies as wild bee making swings and abrupt movements. In the size he is double than a honey bee or common wasp. In the network I did not find photograph that his would resemble. Know does no one what is it?

Look photos in

Sorry for my English
