    The erroneous courtship hypothesis is not based on game theory in that it does not analyze the evolution of strategies.

    Such methods open the way to study individual mating success of butterflies in nature. Spatial acuity of compound eyes has often been inferred from the results of measuring interommatidial angles on the basis that smaller interommatidial angles enable higher spatial acuity Land Last, I try to understand the two forms of contests comprehensively, and propose future directions for research on this issue.

    The erroneous courtship hypothesis is based on two premises: butterflies are not able to inflict significant costs on a non-displaying opponent, and butterflies are not able to fully discriminate the sex of flying conspecifics.

    Chicago: University of Chicago; Because the two females were receptive and they did not resist the male, the degree of similarity between male—male and male—female interactions is not yet sufficiently known in this species. If contestants can impose physical costs on their opponent, the contestants with larger body size are generally expected to enjoy advantages because they can generate larger kinetic energy.
