Hi Bugman. I love your site, and was happy to see some pictures from Canada. Here are a couple I got while taking pictures of wild flowers. I know the one is a goldenrod crab, but what is the other one?
One of the Crab Spiders, Mitsumena vatia, the Goldenrod Spider, is also called a Flower Spider. They are able to change colors to match surroundings. Your example shows what happens when a hapless Honey Bee tries visiting a flower with a concealed Flower Spider. We don’t recognize your other spider.
