This is a common aquatic carnivorous plant around here. I tried to grow it, but I haven't had a long-term success, though. It is supposed to be similar to U. vulgaris, but the shape of the spur is quite different.

We went to a neighbor pond, Ballaine Lake, for a quick fly fishing. Rain was predicted, so there weren't many people fishing in this often crowded pond. While my 6-year-old son was fishing, I found these yellow flowers. I snapped a couple photos while dodging his back cast. Fortunately, he hooked fish instead of human head.
