Phoretic transport of N. kronaueri on workers of a certain size. Size range of Eciton mexicanum s. str. head widths (N = 93) support the findings of Powell & Franks [77], i.e. a bimodal distribution consisting of the typical E. mexicanum workers scaling over a broad head width range, and major workers with a larger and distinct range in head widths. b Mean (dot), standard deviation (solid line), and range (dotted line) of Eciton mexicanum s. str. workers with N. kronaueri attached. Specimens with N. kronaueri attached were collected from two different ant colonies (N1 = 12 workers with N. kronaueri; N2 = 60 workers with N. kronaueri). Image credits: Daniel Kronauer
