| Close up infected aphids on a leaf. Infected aphids are tan or pink, and fuzzy in appearance. Aphid populations in this field crashed in a matter of days. | The tip of the paint brush points to an winged aphid dead from fungal infection (dime for size comparison). This winged aphid is a source of infection for the non-winged aphids surrounding it in the picture. |
