HighlightsPair formation in Enchenopa treehoppers involves male–female signal duets.These duets provide information about the mating decisions of nearby individuals.We tested for mate choice copying in Enchenopa with duet playback treatments.Enchenopa mate preferences were unaffected by the playbacks.No copying may represent selection for fixed preferences, instead of no opportunity.In mate choice, social learning may take the form of mate choice copying or anticopying, whereby observed mating decisions are either mimicked or avoided. Alternatively, independent mating decisions may be based on innate preferences or early life social learning. While mate choice copying is widespread among some animal taxa, research in arthropods is limited and results are mixed. We tested these hypotheses using Enchenopa treehoppers (Hemiptera: Membracidae). Enchenopa males produce plant-borne vibrational advertisement signals and females express their mate preferences by selectively duetting with males. Individuals on the plant can monitor these public signals during pair formation. We randomly assigned females to treatment duets consisting of either unattractive or attractive male signals, followed by a long female treatment response (enthusiastic), a short female treatment response (reserved) or no female treatment response. We described the test females' mating preferences before and after the treatment duet. We found that female mate preferences were not affected by the treatment duets. Instead, females had consistent individual differences, which supports the independent mate choice hypothesis and rejects both social learning hypotheses. Our findings suggest that independent mate choice does not necessarily represent a lack of opportunity for social influences from the immediate social context of mate choice.
