The link wouldn't work for me for some reason, but judging by

the
description it could possibly be azalea lace but.
Check under the leaves and if you see small "fly" type insects,

whose wings
look almost like lacework (and seethrough) that would be lace

bug.
If so you can spray with a systemic insecticide. I know Rogor

is one here in
Australia, you may have it over there. If not ask at a nursery.

Just watch
it as it is pretty potent to humans. The leaves will not

recover if it's
lace bug, and it may loose affected foliage, but it will come

back.
Good luck

That's rather drastic treatment for lacebug. A soap spray or a
pyrethrin spray (with or without soap) will do just as well and
at a lot less risk.


Yeah, maybe it is on a bonsai, drastic that is. Perhaps I should have typed
post a little better. The treatment I suggested will not hurt the plant, or
cause foliage to drop. The foliage will drop due to the lace bug. It's just
at work when our Azaleas are infected by lace bug the only treatment that
seems to work is rogor (or similar/equivalent). Our Azaleas may be unlucky
to get lace bug once a year max. The problem is we have used organic sprays,
and were actually a test area for them, and if you did not get the spray to
contact every bug reinfestation occured shortly after. Same happened with
the Aphids. Then again, being a bonsai, ie small, it would be a lot easier
to get all the bugs. Sorry, it wasn't something I thought of till now.
For the original poster it's not lace bug, as the second link worked for me
and I saw the bug. Looks to be a aphid. They could have caused the dots,
that I'm not sure about. Certainly the bug is not scale, as scale are
usually hidden under a coating of some sort (sometimes wax).
If you really want to go organic, and this will work, introduce predatory
wasps or the good ladybirds to get rid of them. You would have to buy them
from somewhere in your local area.

Good luck with it.
