What is this pest?

There is tiny bits of white sticky stuff appeared on the leaves on an acer.  It seems to have a maggot type thing underneath.  What is it please?  Will Provado help remove it?  Many thanks, Mags

    Are they wool aphids? If so provado will do the job.

    Is wooly aphid sticky?  This stuff is.   Mags

    And what is under the white sticky stuff isn't an aphid - more like a small maggot with a brown head.  Sorry, I can't supply a photo.  Mags

    Yes as I remember it's a waxy type of sticky.

    Yes, I googled and  found a couple of pics that look like my problem.  Interesting to see that the bonsai acers at Kew Gdn have the same problem!  Thanks very much, Mags

    Wooly aphid I think.  Anyway, the Provado seems to have done the trick as there is very little of the pest visible today.  Thanks for everyones help.  Mags

    Just take a few minutes to consider before you spray.

    You'll be killing more than a few aphids. Is your need for a pristine leaf enough to warrant the use of a systemic insecticde.
