Gather ye Nectar.....

whilst the Sun shines. Do these bees know something about the weather that we don't. At present the sun is shining, and there are absolutely everywhere.  Maybe before the rain comes back!!
I tried to pick some Lavender, but there were too many there. On this ornamental Allium - (only a small one, ) there were 3 on one head, and the others were covered, as were the purple Liatris.
Maybe it is just something to do with the colour?
And rain just starting as I type !!!!!
