Isotopes can be used to answer a plethora of ecological questions (e.g. trophic dynamics, physiology, dispersal patterns), but many entomologists remain unfamiliar with the methodologies used by isotope ecologists. We will showcase a diversity of isotopic systems and demonstrate the variety of questions that isotopes can help answer.
