My Turk's Cap was starting to bloom recently, but now I don't see any blooms and I think this is to blame. They appear at the tips of many branches just like in my picture.

There is an entry in the bug files (page 1 as luck would have it) for a pest called a Magnolia Scale and it looks very similar to the bugs in my photo.

Anyone know what this is for sure, and how I can eradicate them organically, if possible?
