The honeysuckle witches' broom aphid (Hyadaphis tataricae (Aizenberg)) ... causes unsightly witches' broom distortions on many ornamental varieties of honeysuckle. Terminal leaves and branches are greatly reduced in size, and leaves fold along the midvein to enclose the aphid colonies on their upper surfaces. Bushes can be severely damaged and occasionally die.

The aphids are small (less than l/l2 inch long), pale army green, and covered with fuzzy gray wax. Because aphids are hidden inside folded leaves and covered with wax, the witches' brooms have sometimes been mistaken for plant disease symptoms.
