Results of “contests” between simulated male moths seeking a pheromone source: variation across memory timescale, τ, and plume-crossing probability, P cross , with fixed advance parameter, \(\boldsymbol {{c}^{*}_{1}=0{.}9}\). Other details are as in Figure 11. The plots represent the number of contests won by simulated moths with corresponding parameters, normalized by the expected number if outcomes were random, with two, three or four contestants (left, middle and right, respectively). The overall higher winning metrics for three- and four-way contests reflect the relatively smaller frequency of contests with no winners (i.e., all contestants failed to locate the source). These contest outcomes suggest advantages, at least under simulated conditions, for behaviors with longer memory timescales (larger values of τ): In two-, three and four-way contests, success increases with memory timescale.
