The greenbug, Toxoptera graminum (Rond.), was observed on five host plants not previously recorded. It was found to oversummer on western wheat grass, Agropyron smithii (Rydb.), during 1959. The aphid was observed in both the normal and the aestivating forms on this grass and migrated from it in the late summer to large volunteer wheat clumps and from those to wheat fields in the fall.
