The growths appear as though they are some sort of cocoon but are actually deformed growth caused by the tree’s reaction to gall mites feeding on the leaves. I have seen this to a lesser degree in my own yard in Washington.

Great visual image, WD.

I think a lot of people have no idea what is affecting their trees until they see a clear picture like this one.

I thought the pear rust structure was nasty.  That looks really disturbing.  I might have to cut that all off and burn it just for peace of mind.

I found galls on Lombardy poplar leaf stems in Puyallup. Apparently caused by aphids. The gall is a spiral with small chamber where the aphids live. When you tug on the stem  the gall uncoils.

I found a new pest on my Seigerebe grape leaves. I believe that they are grape leaf blister mites. The top surface of the leaves have raised blisters and the bottom side has silk patches, like spider egg sacks. I do not see any of these pests on my seedless table grapes - interlaken, glenora, etc.
