Thanks all---

I have an update....Been outside sorting EVERYONE'S orders this morning.

I had left the affected tip leaves on the paper towel outside--and this morning the
paper was covered (well--a lot of them) very, very tiny black insects of some kind.
No bigger than a grain of sand--but they were moving--almost too slow to detect.

I took some pictures--but even in a macro mode, you will not see anything to go by.
Haven't uploaded them yet. I may go out with a magnifying glass and see if I can make something out.

FlowAjen--These trees all have been planted on the curb strip in 1972. A long life!
So many of the hollow stems have been homes to nesting birds.
They have had their share of road salt as the plows go through.
This curling of the leaves has never been there before. Just now.

Sally--I have spell-check--so my spelling is OK. But my fat fingers many times hit 2 keys at once.
Then I have to correct it.

Will check in a bit later again. Gita

Picture is taken from the front of my house (that's my car) towards the West.
You can see about how the trees look. This was taken summer of 2010.
