Cinara obscura
Dark Spruce Stem Aphid
Cinara obscura is a species of large aphid in the family Aphididae, commonly known as the Dark Spruce Stem Aphid. It is a conifer-feeding aphid that infests spruce trees (Picea species). Like other members of the genus Cinara, it possesses a long piercing-sucking beak adapted for tapping into phloem tissues. The species overwinters as eggs on host needles. It produces honeydew, which attracts ants and wasps and supports sooty mold growth.
