Species that increase the number of sons while the number of daughters remain constant or decrease. Thirteen data sets, each connected by a line, from 13 species with line and symbol outline colour indicating the genus and symbol fill indicating the foundress number. Symbol shapes are as follows: B. nipponica (circle), C. fusciceps (rombus), C. galili (circle), C. solmsi (square), Elisabethiella baijnathi (circle), Eupristina koningsbergeri (circle), Pegoscapus franki (circle), P. lopesi (square), P. piceipes (up triangle), P. tonduzi (down triangle), Platyscapa awekei (circle) Tetrapus ecuadoranus (circle) and Tetrapus sp. ex Ficus insipida (down triangle). Confidence intervals are not given as these are normally not reported. The grey line and circles indicate clutch compositions that would make Herre’s nh assumption [17] and Eq. (2) correct at the same time for an imaginary single-foundress clutch size of 180 and nh = 2. Note that the scales of the axes differ. Details in Additional files 1 and 3
