This PDF file includes:

  • fig. S1. Illustration of a helping ant and different injury types, as shown in Fig. 1.
  • fig. S2. Effect of stridulation on rescue behavior.
  • table S1. Statistical differences in injury-type frequency (Fig. 1A) and speed (Fig. 1B) in injured M. analis ants (Kruskal-Wallis test, followed by pairwise comparisons with Bonferroni-corrected Dunn’s test; n = 20 per test).
