Probably a type of scale insect.
There are thousands, and they infect all kinds of plants. I've got a cousin who lives in orange groves.When you stood under some of the bigger trees, it felt like a constant drizzle. They chopped the trees down. I think for the bugs on citrus trees, the assassin bug is a good control.
But, if you're feeling rain...it's probably too late.
I'm thinking it's a sucking insect. Some examples of sucking insects are scale insects, aphids, leafhoppers, spider mites, and thrips. These insects suck the liquid out of trees, while being immobile on the tree.
These insects excrete a sweet, sticky substance known as honeydew, which is unprocessed plant material. Honeydew will cause mold to form on your tree's leaves, so removing the insects is vital for your tree to stay healthy. To remove these sucking insects, you will have to use one of the following: 1.
Insecticidal Soap 2. Horticultural Oil 3. Safer's Trounce 4.
Aphid Chaser (for aphids only) For more information, see sources.
I cant really gove you an answer,but what I can give you is a way to a solution, that is you have to find the anglde that you relate to or peaks your interest. A good paper is one that people get drawn into because it reaches them ln some way.As for me WW11 to me, I think of the holocaust and the effect it had on the survivors, their families and those who stood by and did nothing until it was too late.
