Red bottomed bee

A week ago I blipped a red bottomed bee that then disappeared. I presumed it had died and fallen down behind somewhere as the door was closed but today I saw this. It was alive but was moving only very slightly. I gave it some sugar dissolved in water and put it out on the balcony. Unfortunately it didn't make it, when I checked on it later it had fallen into the little bit of water.

Had to stay very late at school to help my head of department with the China applications. Ran in the evening and drinks with the girls before school on Saturday.
