I bet there was..How exciting for you. My one and only bee seems to have disappeared. I think I might get one of those mason bee houses I've seen in catalogs to try to lure some wayward bees to my yard.

You can make a mason bee house by drilling holes in a block of wood. Do a google search to get the exact size and depth of the hole.
Attracting your own bees seems to be the way to go. I think all the clover we have is luring bees (and deer!) our way. My uncle used to be a bee keeper. Farmers would beg him to bring hives to their farms for pollination. The uncle also made honey from his hives. It was very labor intensive and since he was a small operation, he never got enough money per jar to make up for the time and expense he had in it. He was a wonderful uncle ... funny, smart in a common sense way (didn’t finish high school), could build/do anything, and he had the kindest heart. The last thing he did before he died was deliver a shipment of queen bees to their new hives. Whenever I see honey bees, I can’t help but think of him. Although we’re seeing a lot of honey bees this year compared to almost none in years prior, the bumble bees are everywhere ..... and I’ll gladly take bumble bee help if they’re willing to do it and seeing the one in/out of the squash flower made my day!
