Abstract

Lay SummaryHow genetic variation is preserved is a central issue in evolutionary biology. In many species of damselflies, females come in distinct heritable color varieties. We found that in an Iberian damselfly when subject to stressful male harassment, fecundity decreased in one kind of female but not in others. Our results, together with previous observations, suggest a scenario where differential fecundity, male preference, and fluctuations in male abundance play an important role in maintaining this variation.
