Aphidoidea
Small, soft-bodied insects that cluster on new growth and undersides of leaves. They suck plant sap and excrete honeydew, which attracts ants and promotes sooty mold growth.
Tiny (1/16 to 1/8 inch), pear-shaped insects in green, black, brown, pink, or yellow. Often found in clusters on stems and leaf undersides. May have wings or be wingless.
Curled, yellowed, or distorted leaves. Stunted growth. Sticky honeydew residue on leaves. Black sooty mold. Wilting plants despite adequate water.
Reproduce rapidly, with females giving live birth to nymphs without mating (parthenogenesis). Can produce multiple generations per season. Overwinter as eggs on woody plants.
Avoid over-fertilizing with nitrogen. Encourage beneficial insects. Use reflective mulches. Inspect new plants before introducing to garden.
