Still there are lots and lots and lots of bees on the Phacelia and none on the beans. Somehow need to persuade the bees to go for the beans. I once caught a bee and shut it up for an hour with a bean flower to see if I could fix it on beans.They also seem to be interested in the courgettes.
Varying the appearance in a way the bees can see does make sense. It makes it easier for the bees to recognise their own hive, otherwise you find that they tend to drift towards the end hive in a row.
No, just because we see the red doesn't mean they aren't attractive in the ultra-violet spectrum... :-X
