Includes Illinoia rhododendri and others
Pest description and damage Rhododendron aphids are 0.09 to 0.13 inch in length and often spotted first by the cast exoskeletons of the aphids covering buds and sticky new growth. By then the aphids may have flown. They are soft-bodied insects with piercing-sucking mouthparts. Color varies from pink to green. Feeding damage to mature plants is usually minor, but can compromise the vigor of small plants. Leaves, infested as they expand, are somewhat smaller and distorted with wavy edges. The health of established landscape plants is not threatened by aphid feeding activities.
