Open to bees and butterflies

I couldn't help notice the number of bees and a solo butterfly enjoying the confections on offer here. How do they know where to find them? It's beyond me. It was hot, today, definitely beyond warm. It changes everything. I said to a near neighbour that I wished it was like this all the time, and she agreed. The golf club have put up a new sign on their practice range. (See extra) I think it is quite nice and shows their humanity. It doesn't say: "People are prohibited/ trespassers will be prosecuted."
