Mating behaviours of male P. mirabilis spiders offering different nuptial gifts (PG (protein fly gift), FG (fly gift), WG (worthless gift) and NG (no gift), data presented as mean and standard error). A) Mating duration, B) insertion duration and C) number of insertions. Statistical comparisons were performed using two-way ANOVA or Kruskal-Wallis test, and the pair-wise comparisons using Student t-test or Mann-Whitney U test, respectively. Groups with the same letter were not significantly different (p > 0.05).
