Lepidopterans (moths and butterflies) sometimes have specialized flying behaviors. Some moths have the ability to do sudden vertical drops when they detect bat sonar, to avoid being eaten. Other species use special flying techniques to attract a mate.When biologists talk about the "cause" of a behavior, they may be referring to two different things. The proximate cause is the sequence of physiological events that lead to the behavior in an individual. The ultimate cause is the adaptive benefit to the animal that allowed natural selection to sculpt the behavior over evolutionary time. Understanding both the proximate and ultimate basis of behavior is important, and different types of biologists may focus on each.What could you study to better understand the ultimate basis of this
behavior? (Check all that apply)
A. flying behavior in related species
B. wing muscle development
C. sensory organs
D. physiology
E. brain structure
F. mating behavior
