雄性新热带兰花蜜蜂从环境中收集挥发性物质，并在腿袋中合成复杂的，物种特异性的气味混合物。这些香水是由男性积累随着时间的推移，并暴露在交配前显示。有人假设，香水是男性基因型质量的指标，女性通过气味的质量或强度来选择配偶。由于缺乏直接的实验证据，我们调查了雄性香水的数量或复杂性是否与雄性（1）大小，（2）波动（左右）不对称，或（3）年龄有关，这些特征在其他动物中已知是性选择的。在墨西哥尤卡坦半岛的旱季和雨季采集了两种黄腹真舌鱼（Euglossa dilemma和Euglossa viridissimacolated）（总N = 768）的左右前翅（细胞节距为1和2，翅磨损为3）。在排除季节的影响后，翅的大小与两个物种的香料提取物的数量或复杂性无关，这对E的大小和香料负载都有积极影响。困境除雨季外，翅的不对称性也没有影响。viridissima，其中它与香料的量正相关（而不是负相关）。翅膀磨损，兰花蜜蜂的一个既定的年龄指标，有唯一一致的整体效果，在这两个物种的香水量和复杂性呈正相关。这与香水是男性生存能力的诚实指标的想法一致。
Male neotropical orchid bees collect volatile substances from their environment and compose complex, species-specific odour blends in leg pouches. These perfumes are accumulated by the males over time and are exposed during pre-mating display. It has been hypothesized that perfumes are indicators of male genotypic quality and that females chose mates by the quality or intensity of their odour. Because direct experimental proof is lacking, we investigated whether the amount or complexity of male perfumes is related to male (1) size, (2) fluctuating (left–right) asymmetry, or (3) age, traits that are known to be sexually selected in other animals. We measured left and right forewings (cell node distances for 1 and 2, wing wear for 3) ofEuglossa dilemmaandEuglossa viridissimacollected during dry and rainy seasons on the Yucatán peninsula, Mexico (totalN= 768). Wing size was not related to the quantity or the complexity of perfume extracts in either species after excluding the effect of season, which positively affected both size and perfume load inE. dilemma. Wing asymmetry had also no effect, except in rainy seasonE. viridissima, where it was positively (not negatively) correlated with the quantity of perfume. Wing wear, an established age indicator of orchid bees, had the only consistent overall effect, being positively correlated with perfume amount and complexity in both species. This is in agreement with the idea that perfumes are an honest indicator of male survival capacity.
