女性选择在性选择中的作用已经确立，包括女性根据多种线索选择配偶的认识。这些线索可能包括男性表型的内在方面以及与男性相关的环境方面。在领土性脊椎动物中，潜在配偶的空间位置的作用已经得到了很好的研究。然而，尽管它们是性选择研究的实验室模型，昆虫根据位置选择配偶的可能性几乎没有被研究过。我们在西班牙北部的草地上研究了一个自然种群的单独标记蟋蟀（Gryllus campestris）。成虫通常每隔几天就会在洞穴之间移动一次，这使我们能够研究如何通过它们所占据的洞穴来预测雄性的配对成功，而不依赖于它们自身的特征。我们观察了整个10个独立的繁殖季节，以提供复制，并确定这些因素的相对重要性在多年间是否稳定。我们发现男性的身份和他的洞穴的身份都会影响他与女性配对的可能性，但洞穴的影响始终更大。此外，这两个因素相互作用：雄性个体的相对吸引力取决于它所占据的洞穴。我们的发现证明了自然和性选择特征之间的密切互动。这也表明，配偶选择研究不仅可以考虑明显的第二性特征，还可以考虑更隐蔽的特征，如微生境选择。我们的研究表明，雌性昆虫选择与雄性昆虫同居时，更看重的是他住在哪里，而不是他是谁，但两者的结合更为重要。我们知道，雌鸟经常根据雄鸟领地的质量来选择雄鸟；我们在西班牙草地上观察蟋蟀与异性共用洞穴长达10年，发现昆虫也能做到这一点。
The role of female choice in sexual selection is well established, including the recognition that females choose their mates based on multiple cues. These cues may include intrinsic aspects of a male’s phenotype as well as aspects of the environment associated with the male. The role of the spatial location of a potential mate has been well studied in territorial vertebrates. However, despite their role as laboratory models for studies of sexual selection, the potential for insects to choose their mates on the basis of location has scarcely been studied. We studied a natural population of individually tagged crickets (Gryllus campestris) in a meadow in Northern Spain. Adults typically move between burrows every few days, allowing us to examine how pairing success of males can be predicted by the burrow they occupy, independent of their own characteristics. We observed the entirety of ten independent breeding seasons to provide replication and to determine whether the relative importance of these factors is stable across years. We find that both male ID and the ID his burrow affect the likelihood that he is paired with a female, but the burrow has a consistently greater influence. Furthermore, the two factors interact: the relative attractiveness of an individual male depends on which burrow he occupies. Our finding demonstrates a close interaction between naturally and sexually selected traits. It also demonstrates that mate choice studies may benefit from considering not only obvious secondary sexual traits, but also more cryptic traits such as microhabitat choice. We show that female insects choosing to cohabit with a male place more importance on where he lives than on who he is, but the combination of the two is more important still. We know that female birds often choose a male based on the quality of his territory; our 10 years of observing crickets moving around a Spanish meadow to share burrows with members of the opposite sex, reveals insects can do the same.
