Its by no. mean a crisis with my inquiry but I have two things Im trying to fiqure out.
1. I have multiple jasmine plants that have suffered since Oct. Ive sprayed with Tritek oil and since not getting better Im getting ready to use Stylet Oil. We are going organic.
So pics of Jasmine Leaf.
1 A. I can gently scrape structures and they do not look like aphid. Is this powdery mildew?
1B image of insect with green body very small and quite a bit flying in Jasmine.
2. I have a think a blue spruce? I remember going out west last summer seeing what moths have done to Colorado and New Mexico . Not the pondersa beatlle but a moth.
looking at the images with pine needles there is a bug that looks similar to whats on Jasmine but they seem different.
So can someone please give me some input on Jasmine and what bug and things on leaves are?
and should I be concerned about the flying inscect in pine tree? Blue Spruce?
Thanks for any support!

I am not convinced it is scale on the jasmine leaf as scale ranges in color from tan to brown. If the Extension Plant Clinic was open, I would send you there so the master gardeners could look at the insects under the microscope. Given it won't be open soon, I am giving you a link to a University of California publication on scale: http://ipm.ucanr.edu/PMG/PESTNOTES/pn7408.html
If it is scale, there would be a sticky residue exuded by the insects. Similar residue is found in an aphid infestation. The article suggest insecticidal soaps or neem oil for extensive infections. Follow all label directions on the insecticide you choose to use.
The insect on your spruce needles looks like a leafhopper resting. Looking at the healthy needles, I would say you should not be concerned about a broad infestation. To help you identify your tree as a spruce, follow this link from OSU: https://oregonstate.edu/trees/conifer_genera/spruce.html
