I have no idea how many tiny spider webs I have noticed in the grasses and low plants over the years. They seem to be most numerous in the fall or I seem to notice them more in the fall.
Anyway, this morning I had a closer look. There seem to be tiny spiders under the webs. How could I have not noticed until this morning. I took several photos. This one seemed to be the best.
I believe it is one of the "Sheetweb Weavers," and possibly the spider called the Filmy Dome Spider (Neriene radiata).
