Species that reduce the number of daughters and sons remain constant or decrease. Seventeen data sets, each connected by a line, for 13 species with line and symbol outline colour indicating the genus and symbol fill indicating the foundress number: Symbol shapes are as follows: Blastophaga nipponica (circle), Ceratosolen capensis (circle), C. fusciceps (rombus), C. gravelyi (square), C. marchali (up triangle), C. solmsi (down triangle), Kradibia tentacularis (circle), Pegoscapus aerumnosus (circle), P. herrei (rombus), P. jimenezi (square), P. longiceps (circle with +), P. silverstrii (up triangle) and Pegoscapus sp. ex Ficus crocata (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. The dotted lines are for two species where number of sons and number of daughters were both divided by 2. Note that the scales of the axes differ. Details in Additional files 1 and 3
