Sexual conflict is predicted to generate more rapid reproductive isolation between larger populations. While there is some empirical support for this, the data are inconsistent and, additionally, there has been criticism of some of the evidence. Here we reanalyse two experimental-evolution datasets using an isolation index widely applied in the speciation literature. We find evidence for reproductive isolation through sexual conflict in
Sepsis cynipsea
, but not in
Drosophila melanogaster
, and this occurred to a greater degree in larger populations, which is consistent with previous findings.
