Balsam Twig Aphid
Twisted and curled needles are the most apparent damage from feeding by the balsam twig aphid. Feeding can also cause roughened bark on the twigs. Extensive feeding can cause a general decline and reduced vigor of the tree, yet in many cases is cosmetic and not particularly damaging. The major problem is that curled needles reduce the marketability and value of Christmas trees. Balsam twig aphids also produce honeydew, a sticky material that drops to needles and twigs below. At times the honeydew can become a growth medium for sooty mold, which turns the needles and twigs black.

Cerceris fumipennis “The Smokey Winged Beetle Bandit”
Cerceris fumipennis is a solitary digger wasp (crabronid) native to eastern North America. It is a predator almost exclusively of adult beetles of the family Buprestidae. This wasp gathers many species of native metallic wood-boring beetles, as well as the invasive emerald ash borer, Agrilus planipennis (Fairmaire) (EAB).
