Green-striped Spruce Aphid Cinara piceicola

This lone three-legged aphid was beaten out of spruce. It was viviparous, giving birth to 9 nymphs in the pot, although I didn't find these until they had all shrivelled up. The dark stripes down the sides of the dorsum aren't obviously green but you can just make out a waxy central stripe (easiest to see in the side-on photo).
