Caught in a net by sweeping the water along the edge of a small pond. Moved it to a small container photographed it a couple hours later. In some of the photos it was swimming under water but it get crawling out of the water so some of the photos are taken while it was walking on a piece of gray plastic.
Broad green leaves, small buds, with small white flowers.
Certainly a weed, but I like it, and it is the only one in my yard.
I have no idea what it is and was looking for some help.
