Scale insect my friend. I have discovered plenty on my trees this year. Squish the beggars and look out for smaller ones as well.

is that the only tactic? I can't see the bleeders. Is there any scale insect napalm I can frag them with?

Lime Sulphur at 7 to 10-1 on a cotton bud works well as does meths. I squish it with my fingers and remove as much as possible then use LS as above.

My Siberian Elm gets it every year and with either of the above I have never had a problem.

Look for a systemic insecticide with the active ingredient Imidacloprid. It is listed for scale.

Elms can play up when systemics are used - and is not recommended by many experts. Your tree though.
