Eomacrosiphon nigromaculosum (MacDougall)
After almost 30 years of avidly collecting aphids on wild roses, knowing this species was out there somewhere and feeling frustrated at not funding it, in 2017 I finally stumbled on it just outside Lakeview. It was growing on a patch of roses on a cold slope in a steep, braided mountain stream. At first I didn’t know what it was, having never seen a photo of E. nigromaculosum. I was also thrown off by the short siphunculi that look more like a Brachycaudus or big Dysaphis than what I expected of E. nigromaculosum. Eventually I realized what I had found, and concluded that the short siphunculi were owing to the fact that these specimens were fundatrices (this stage often has short siphunculi in Aphidinae). Subsequently I was able to collect summer apterous females, and in early September, oviparae and males.
