Table of compounds. Concentrations of 32 compounds that constituted 99.06% of the chemical profiles of workers (N = 44) across colonies evaluated by a similarity percentage analysis (SIMPER) on Bray-Curtis distances. In addition, concentrations of non-isolated (Sf 0 d; N = 63), six days isolated (Sf 6 d; N = 12) and nine day isolated silverfish (Sf 9 d; N = 56) across colonies are shown.

Video of M. ponerophila. The video shows M. ponerophila together with host workers and brood in an artificial nest site. One silverfish individual (in the foreground) rubs its own body intensely on that of an ant worker, presumably to acquire host CHCs.
