This project will continue a quarter century of                         investigations that have used checkerspot butterflies as a model                system to understand the ecology, genetics, and evolution of                    insects.                                                                                The work has already led to numerous findings that are                  important to the design of rational pest control strategies.                    During this grant period, research will concentrate on four                     general questions.  First, how does the behavior of adult                       butterflies influence the evolution of their populations?                       Second, how does climate influence the size of the butterfly                    populations?  Third, how do butterflies colonize "empty" areas of               habitat and how likely are newly established populations to go                  extinct?  Fourth, how do populations in different places become                 genetically distinct?  All of these are both theoretically                      important and also relevant to economic questions.
