My understanding that plants may mimic aphid infestation arrived in a flash when Moshik Inbar and I were teaching field ecology. The class was large, so each of us had about 25 students and we sat about 20 meters apart along a stream that emerged and flowed slowly from a spring in cave. At the same moment, we spotted the same plant species (Paspalum paspaloides = P. distichum; Poaceae), a wind-pollinated plant, with numerous dark anthers that look like aphids (Fig. 57.1). We each picked a flowering branch, and without saying a word lifted it up to show the other. We immediately understood each other and discussed it at the end of the field day.
