Many aphids prefer to feed on young, succulent growth.
Some feed in sheltered locations, such as inside leaves that they have caused to curl or become distorted. Aphids attack trees and shrubs of all kinds but do not usually seriously injure them. New plant growth may become distorted or stunted before predators and parasites decimate the aphid population. The greatest damage may be from the sticky, sugary aphid excrement called honeydew. Honeydew may fall on automobiles or furniture below infested trees.
