Figure 15.17 Fungal control of the perching behavior in the yellow dungfly. (a) Compared to uninfected dungflies, infected dungflies perch higher on plants. Error bars are 1 standard deviation. (b) Uninfected dungflies never perch on the underside of a leaf whereas infected flies do so 91 percent of the time.
