For bees, it would still speed things up - just yank
> the gut and look for color.

My main crop comes from wild raspberries. When the berries are overriepe and 
we get a warm, dry weather the sugar concentration in old berries goes up so 
much that bees start to eat the berries.  At this time there is often no 
nectar coming from flowers anymore.

The honeysack turns red and is easily visible from the outside of the bee. 
Its located in abdomen close to the middle section of the bee.  No need to 
kill and look. This can be seen already in when sun shines to the top bars 
of opened hive but much more clearly on the bees at the car window.

This year this phenomen was stronger than normal. We even got some cells 
full of red 'honey'.As bee advicer I received several phone calls from 
concerned beekeepers about red honey and a strange disease that is turning 
bees red :)

So if you find right colour it might work so well that you need just to look 
at the bee. If someone finds it I would like to know the answer too.
