You all know this insect. He is a pretty stocky fellow—black and yellow. And he tends to fly in a sort of unprogrammed way.
Most insects fly as though they know where they want to go, but the bumblebee seems to fly in a sort of clumsy way. He even will fly right into things, and if he lands on something, he seems to move around as though he was lost.
I suppose this is sort of, well, bumbling.
