Each individual male of P. johnsoni can employ any of three mating tactics, depending on the type of female (adult or subadult, inside or outside nest) encountered: (a) adult, outside—vision-dependent courtship; (b) adult, inside—vibratory courtship; (c) subadult, inside—cohabitation.
Pursuit time (interval between the beginning of courtship and the beginning of copulation) recorded in the laboratory was greater (mean: 16 min, max.: 3 h 44 min) for adult females inside nests than for ones outside nests (2 min, 14 min, P<0.001; Fig. 2).
Cohabitation in the laboratory and nature usually lasted ca. 1 week.
Postmount copulatory latency (period between when male first mounts the female and when copulation begins) was usually longer for females inside nests (mean: 3 min, max.: 34 min) than for females outside nests (0.4 min, 5 min, P<0.001; Fig. 3).
Male persistence (courtship duration when the female did not mate) was greater with females inside (mean: 5 min) than with ones outside nests (3 min, P<0.01).
