Whats this bug?
Bugman,
The leaves of my Norway Maple are filled with these. A friend tells me they are Mealy Bugs but they are unlike any Mealy Bug I have ever seen or have been able to Identify. The white mass is approx. 1/4 – 3/8 inches long and has what appears to b a brown scale like "cap" at one end. Any help is greatly appreciated.

Hi Alan,
You have a type of Cottony Scale insect from the genus Pulvinaria whose members are characterized by a naked adult female (the scale) who excretes a large cottony egg-sac beneath or behind her body. The Maple-Leaf Pulvinaria, Pulvinaria acericola is found on maple leaves which your photo beautifully illustrates. You might want to try to control the outbreak by checking with a local nursery.
