I checked for spider mites and saw none on any of the webs. Here are 4 photos I took of various webs. They are difficult to see because they are so transparent and provide little contrast against the plants. The first and second photos show webs in the middle of ivy. The 3rd and 4th photos are in the middle of an evergreen ground cover. The webs are also on my lupine, hibiscus, roses, crape myrtle, petunias, and many more plants of all varieties, but I couldn't get a decent photo of those.
