Survival plot of proportion adults alive vs. time since adult emergence and anlysis of survival of adults. Cox regression: Density: Wald χ2 = 56.57, df = 1, p < 0.0001; Sex: Wald χ2 = 72.04, df = 1, p < 0.0001; Density x sex: Wald χ2 = 1.70, df = 1, p = 0.1928; Wing length: Wald χ2 = 64.04, df = 1, p < 0.0001; Spatial block: Wald χ2 = 641.63, df = 19, p < 0.0001. Censored observations were adults that escaped during longevity trials. H = High density, L = Low density, F = female, M = male.
