Update on April 29, 2021
The digital microscope came on April 29, here is one of the videos from today. The mites are very small and rectangular. A few of them here:
I lost a number of young persimmons last year. This year I am watching them very closely. A young Texas persimmon tree just started to bloom, and I could see some fine webs on the leaves. After shaking the leaves on a white paper I found a few thrips, an aphid, but could not see any mites. It took me a good hour and a real camera with a zoom to get a dissent portrait of just one mite. There are many of them, but I would need a camera stand and maybe a microscope to get better pictures. I do not know the species name, but hopefully someone can ID these.
