After writing yesterday I decided to mow my lawn that was covred in leaves. As I was mowing I noticed what appeared to be a light blue smoke coming from the mower and drifting into the air. On closer insepection and moving leaves aside the lawn was covered with these blue aphids that caused the blue haze-- all dead. On taking a closer look at lawn and trees there were dead aphids on the tree trunks not folige. They were massed all over all rough surfaces as if there were spider webs that held them in place. My mercury vapor garage light was covered at least a half inch thick on the large bulb itself and below it thousands of dead aphids.

I too would like to know the nature of this infestation and if it occurs in other locations .....

Hi Bill,
Found a few other sites that have info that may apply.
http://oregonstate.edu/dept/nurspest/woolyashaphid/biology.htm
Some of the pictures are at least similar. Woolly Ash Aphid
The other info relates to the Woolly Apple Aphid
http://www.hortnet.co.nz/key/keys/bugkey2a/nowings/mobile/3legs/waaapt1.htm
Apparently this aphid is becoming a problem in Washington for apple growers. Again some of the pictures are very similar. The information pages on this site tell a lot about the life cycles.
Do they grow apples anywhere near your location? A search on "Woolly Apple Aphid" bought up information from Washington State University on various programs in process to make trees resistant to this aphid.

My insect looks like a very young nymph, except for the missing mouth.
2 days have passed now with no visible activity. By the way, yesterday I left a response to your note on my winged picture.

bye and best regards.

Paul,
There are still a few flying around and on calm sunny days there seems to be a small influx of them. But we have had some fairly strong winds that keep them out of sight. Seems you have been doing a lot of surfing to come up with the sights and information you have.
We have apple orchards 50 miles west of here that extend clear over into Wenatchee the apple capital of the world.
Haven't been able to catch up to the local 'oligist. But will continue to try.
Thanks for all your sought out information.
Take Care--------------
To go to my sight just type in "zBugs" in search..

Apparently when they first appear they do not have the white on them
till a week or so later. On putting Wooly Aphids in search and observing those pictures I had decided they were not the Wooly Aphhid.
But those must have been the exteme as I have never observed the white as it appears in these pictures, and have lived in this area for 75yrs. -- But today almost 5 days later I looked with the magnifying glass and did see a small amount of white on the abdomen.
My Son-inlaw said that they settled on his lawn very thick and it
appeared blue-ish. --( Ahh the wonders of nature.)
