What is this ON a plant?
This is on one of my mother's maples. What is it and what should she do about it?

The silver maple capitate mite ( Vasates quadripedes ) is a herbivorous mite from the family Eriophyidae . Monophage, haloformer, damages North American maples: silver maple ( Acer saccharinum ), sugar maple ( Acer saccharum ), red maple ( Acer rubrum ). Induces the formation of small capitate galls on the leaves. Comes from North America. In the 20th century, with planting material, it was brought to Europe. Recorded in 1957 in Latvia, currently widespread in Europe on silver maple ( Acer saccharinum ).
