In experiments with the backswimmer (Notonecta glauca), a predatory insect, and two types of prey species, isopods (Asellus aquaticus) and mayflies (Coeon dipterum), predator preference seemed to be affected by the percent of mayflies. What explains the results presented in the figure? What type of functional response is being demonstrated?
