Tonight we have a couple of native bees photographed this summer at Shaw’s Nature Reserve. I may very well be incorrect, but I believe the bee pictured above is a Mining bee in the family Andrenidae. I would love to know how much pollen is taken away in a season by these guys.
The final two photos show a sweat bee (Halactidae). These are quite challenging to photograph, but worth the effort.
