Pest description and damage This aphid is 0.1 inch long, usually shiny black, but also may be dull black to mahogany. It can be found on new growth or on winter buds. Infestations may be severe in any season and are often a problem on plants growing in protected places. Aphids tend to feed in colonies and are often found on the most succulent plant tissues. Feeding damage to shrubs, trees and mature plants is usually minor, but can compromise the vigor of the bud and expanding tissue.
