Status achieved by Maculinea rebeli within natural and unnatural Myrmica host societies. (a–h) The order that disturbed workers rescued ant brood or butterfly larvae 3 h and 7 days after adoption. Each replicate involved a choice between kin ant pupae (open circle), large kin ant larvae (open square), small kin ant larvae (open diamond), Ma. rebeli larvae (filled circle). Boxplots show means of median orders of rescue (symbol), 25–75% quartiles (box), and first and last individuals (tails); ‘nr’ = per cent Ma. rebeli larvae not retrieved by ants after 30 min. All treatments showed significant differences in the order in which items were retrieved (Kruskal–Wallis, H = 10.38–25.84, d.f. = 3, p = 0.016 to < 0.001), with fewer Ma. rebeli rescued than ant brood in (a–d,f and g) (z = −12.83 to −46.66, p < 0.001). After 7 days with their natural hosts (e,h), Ma. rebeli were rescued first equal with kin pupae (Mann–Whitney W = 38.5, p = 1.000; W = 24.0, p = 0.5309, respectively), significantly ahead of kin larvae (p = 0.024, 0.027).
