Could be a Buddleia leaf weevil, Cleopus japonicus, considered to be a bioloogical control for the invasiveness of butterfly bushes, particularly in NZ and Australia where the plants are noxious weeds. I am not aware of them being very common in the US but perhaps they are being employed for the same purpose (Buddleia is an invasive species on the west coast and beginning to become one in other areas). And the only garden weevil I am aware of that can fly!

It certainly looks like mites. If indeed it was mites the damage was already done before you sprayed. The fact that you sprayed Trilogy (which is a neem product) and soap does not remove the damaged from the leaves. Your leaves will look like that probably for the rest of their lives. If the mites are gone the new leaves will look normal. You might consider starting a regimen to walk your grove to carefully inspect for any potential problems at least weekly. It is also a good idea to start a data base of any problems, where they occurred, what time of year, the date the problem was noticed, and treatment given and results. Many growers feel that by doing this they get a heads up of what to be on the look-out for during each season.

you got to give us something to work with ... facts .... big city name ... transplanted.... or seeded right there ... if planted.. how long ago ... etc.. etc.. etc ... soil looks sodden... did it just rain.. or are you water that much??? is it just this one plant.. or everything in the garden??? based on the little you provided.. it looks like stress ... ken ps: many lettuces can be planted all summer long ... just plant more ....

Interesting question and this response is speculative. Certainly living things will exist in the shredded bark and chips. As the wood debris (chips & bark) decompose there'll be even more living things present. It's an assumption that the cherry died of a disease which is transmittable through the new mulch. It may be the disease needs cherry sap, cambium or some other part of the living tree, too, so that the invertebrates, fungi, etc. won't spread. If existing cherry trees are adjacent to the felled tree, then I would expect the risk is greater. If there are no other cherries near or no cherries at all it's probably safer to leave the mulch. I tend to think that mulch is helpful rather than harmful? It might also depend on the region, climate and species of tree. We planted over 30 trees the year-before-last and there's no evidence that the redwood mulch causes any increase in pests or fungi. Our area is dry (Rocky Mtn.) and NJ may be different in this respect? All of our trees are healthy but they are conifers and as can be seen they are resting in deep mulch.
