CHC resemblance of ecitophiles to host workers. NMDS plots visualizing CHC profile similarities between host ants and ecitophiles in one colony of a Eciton burchellii and one colony of b E. hamatum (for other colonies see Additional file 2: Fig. S3). Chemical profiles of all Eciton workers in the community and c Vatesus adults and larvae, d Tetradonia beetles, e the silverfish Trichatelura manni, f and the ptiliid beetle Cephaloplectus mus. Grey dashed boxes contain host ants and those ecitophiles that were collected in colonies of that host(s), except for Vatesus larvae in c and Tetradonia laticeps rove beetles in d, which were not assigned to host ants via grey dashed boxes. Vatesus cf. clypeatus sp. 1 larvae were collected from E. vagans (N = 14 specimens), Vatesus cf. clypeatus sp. 2 larvae from E. burchellii (N = 13 specimens) and E. hamatum (N = 7 specimens), and Vatesus aff. goianus larvae from E. mexicanum (N = 5 specimens). Tetradonia laticeps rove beetles in d were collected from E. mexicanum (N = 12 specimens) and E. dulcium (N = 17 specimens) colonies
