I found this chap slowly walking up the inside of my window so I took a few pictures on my phone before rescuing him and putting him outside.
I didn't consider that it was anything other than a bee, but while trying to discover its exact variety, I found out that is in fact a type of hover fly mimicking a bee. The biggest give aways are the very short antennas and the single pair of wings.
It's good to learn something new every day.
I also realise that it's time to clean the windows again!.
