Fool...ish B

Me probably, but this little chap is too.

I've been trying to tell him (or several others very like him) for days that the weather is going to change and winter will return, but he (or they) simply buzz around, and land on the far side of a flower where I can't blip, or disappear over to next door's garden.

Caught him here though. He was obviously in need of a rest and a wash, and landed on the fence...

Who's the fool now?
