cicada not aphid
They keep the insect count low and kill insects that harm plants
Soft-bodied insects that leave their food source diseased, sap-poor, and unattractive are what aphids are and what the harm is that they do to plants.Specifically, an aphid is a pest that preys upon plant parts. Aphids like to apply mouthparts known as stylets toward holing into a plant's foliage in order to extract phloem and xylem sap. In the process, they make a plant not only look discolored and un-green but also damaged and diseased (because of the viruses which their mouthparts and saliva vector). They additionally will encourage attacks by wildlife -- such as ants -- in search of aphid honeydew droppings or on a quest for habitat -- such as the fungi seeking to establish sooty molds on vegetation.
Lady bugs will eat the aphids, but the ants protect them from harm.
It may not harm you. But it is immensely painful to have any insect in your ear. You have to fill the ear with spirit. It instantly kills the insect. Then your doctor will take out the dead insect from your ear, very easily.

No, unless your pet is an insect.
Insects harm trees by leaving their harmful bacteria which can spoil tree's branch or leaves and some insects are also capable in making whole into the tree's branch.Some insects like termite can spoil trees by eating their wooden branches.
certain species of ants use aphids similar to how humans use cows: they lead them to graze and collect a liquid discharge the aphids excrete from their abdomen. ants also protect aphids from harm similarly to how humans keep their livestock safe from harm.

Sadly it is very likely.
They pollinate trees and shrubs so that they can grow flowers and seeds.
