Can I get some help identifying this insect that has infested?

[ForTheArborist]

Just because the limb is defoliated by an insect doesn't mean it is dead. Trees and limbs that were defoliated especially by insects can push out new leaves the next year. But you already knew that.

Right, and some were left in just that condition, defoliated. Still there was a lot of dead wooding to be done on them.

yes scratch the bark first; if it's gren inside put the saw away.

I do that too.

I am going with Platanus racemosa. FTA, They are everywhere here, how can you not identify this tree. At this time we are seeing alot of Xyllea. It's not killing the trees, but it is opening them up to stress. Dude, I am glad you are not charging for consultations! I told you I have a free Sunset book if you want it. It maybe an Arizona, but I will go with California.

Platanus occidentalis

Platanus racemosa

My SPECIMEN

Those are eggs - the tiny yellow things on the bottom of those leaves at the top of this thread. The insect that hatches is even smaller than that - tiny - yellow - different. Somebody tell me Nuprins, but I have a hard time buying that.

Everybody has said it's a sycamore including all the people I've talked with around here. Nobody has said anything about it being insects instead of fungus or disease.

I looked at the info about the Plane tree, and it's leaf looks just like these I've got. I still haven't seen any fruit on the tree to determine a thing except I see the bark looks colorful on the Planes while the bark on these here looks plain - American Sycamore.

Its not always such a definative answer when you look at the books then compare to the tree. I would say in this case the reason you can't fing an exact match is that the pic in the book is of a fully mature leaf while the leaf you are holding is rather young.
There is a lot of this kind of stuff when dealing with trees as you will see. There also is a lot of crossbreading and gene splicing that can throw you off.

sure looks like a sycamore that fuz is normal too, apparently the tree is in puberty. No idea on the mite but whats the weather been like. Hard to tell from them pics but may be some small signs of anthracnose which could explain limb lose.

I've seen mite activity like that, some aphids may express that way too.

this is the best place for insect pictures, a pretty comprehensive, searchable database. Thi search is just for the word "mite", it ends with ticks and is 659 images total for the search.

Not usually except for the ####ing hazelnut growing out of my hedge, which has been cut back to the old stump for about 8 years and is still putting out suckers each year.

A healthy root system can provide amazing endurance.
