Cinara obscura is monoecious on spruce (Picea), specifically white spruce (Picea glauca) and Engelmann's spruce (Picea engelmannii). Bradley (1953) first described the species after finding them in colonies on the bark of the lower stems of small white spruce growing close together in seed-beds.

Heavy, driving rains can send aphids on a one-way water ride of doom. Heavy rainfall events will also wash away honeydew. Finally, a long, cool spring also slows the development of the “3-Ps”: Predators, Parasitoids, and Pathogens. These natural regulators help keep aphids in check.
