Reviewer 2's Review (Jeremy L. Marshall)

“Overall, this is an excellent field study and it should be published in PLoS One. I applaud the innovative approach to assess sexual conflict in nature. I only have a few comments to improve the clarity of this work.

(1) Add a color figure showing the three color morphs. I know these are else where, but it would really help the average reader to understand your system.

(2) Add 'morph' labels to Figures 2 and 3, to make it easier for the reader to know which lines correspond to which morphs. I realize the information is on the figure legends, but I really think adding these to the figures themselves would really help.

(3) Something to think about: combine the clasping attempt, # of mating, and fitness data into a single 3D figure to show fitness landscapes for the two strategies in 'infuscans' and between the two main morphs. This could help pin-point whether or not the relationship between higher fitness and increased number of matings seen in 'infuscans' occurs in both 'high' and 'low' resistence females. More importantly, you could demonstarte the number of 'adaptive peaks' in the landscape. In the end, this could help provide predictions for future experiments (like, do high resistence females produce higher fitness daughters, relative to sons; or, do low resistence females produce higher quality sons).”
