Insect

Who can identify what kind of insect is this?
It looks like a hybrid of fly and bee to me.
It is too big to be either.

Last week when my son took the clothes in from outside after dried, this insect came along in between the clothes, it flew away right after he put the clothes down.

Look! There's an insect, said I.

Oh! I didn't see it, said my son.

Obviously it didn't see you coming either, said I, we all laughed.

And my son tried to kill it with the flapper, it flew in circles and buzzing sound like a fly, a huge one, real loud, like it is angry or crazy or scary or whatever.
