MYSTERY SOLVED. IT IS PSYLLA
First: This is the best $3.99 that I have spent. I bought this gizmo that fits on the smartphone camera eye and see the photos I took at 30+ magnification
This was a cheapo. I will definitely be looking for a better one.
Second: these things CANNOT BE SEEN with the naked eye. They are smaller than a grain if sand.
THIS ONE WAS ON A LEAF. IT IS TINY. THIS IS AT 30 MAG
I found them by looking at where the jellowjacks were going. These were mainly at the point where the leaf meets the branch. I pulled back the leaf and there they were. You would not see them with the naked eye in 100 years .
SO now the million dollar question.
WHAT do we do now. My pear trees have no fruit.
