Thanks, I looked at the cottony scale online. I need to go back and take a closer look at the tree. I do recall a couple of leaves during my heavy inspection which had a cottony material at the tip edge. I chalked it up to a left over nest of some sort, but maybe it was scale. Those leaves went into the trash bin. Also, what sort of insect is it that spins a white web/cocoon between two leaves. I know I read this somewhere, but can't remember now. I pulled a couple of these leaves off that we're stuck together. I too, originally thought that the beetles were some sort of flea beetle, but in my guide to garden pest book, they looked more like a ground beetle. Just to be sure, I will be showing it to the arborist that I called this evening. I can't take the stress and worry anymore. He comes tomorrow. I will update with his take on the matter. Ken_adrain, I posted about the main issue previously under the tree section. You were kind enough to respond there, but I am still searching for answers.

That one appears to be the egg of the Swallowtail butterfly, to my knowledge the only butterfly that lays its eggs on citrus. The larva, commonly called the Orange Dog Caterpillar, can eat a mountain of leaves. Take it off and smash it. Some people will tell you to move it to a larger, less important citrus; but as it is a major pest of California citrus, I would err on the side of vengeance, not mercy.

Nope. Cast skins (empty) of aphids. Wash them off to get rid of the still alive aphids I see.

Unfortunately the egg only dried up. The leaf looked ok. I’m not sure what happened. I saw a video on harvesting the eggs and protecting them from outside predators. Do any of you recommend just leaving the leafs on the plants? I have a lot of lizards/ small wild life and I don’t want them eating all the eggs. Also I have a few caterpillars on a passion vine and a milkweed . Should I take them off or are they ok to leave ? The plants seem to be ok despite the few caterpillars eating them
