Mindarus abietinus Koch, 1857 - (balsam twig aphid)
This aphid is a pest of fir trees in North America and Europe. Infested trees have twisted needles and Christmas trees can have a reduced sales value. Sooty mould may form on heavily attacked trees.
Eggs are black and covered with wax filaments. They are laid at the base of needles or in cracks of the bark during the summer. The eggs overwinter and hatch in spring. The first generation feeds on 1-year old needles and gives birth to live offspring, from which wingless adults emerge. The second generation feeds on the new needles and causes most of the damage. Subsequent generations produce again wingless adults or winged adults. The latter migrate to other trees and finally lay overwintering eggs.
