臭虫（Megacopta punctissimum）的成虫，根据雄性的群居习性，在寄主植物上交配聚集。一只雌性被释放到一根茎上，茎上聚集着 2 对交配者和 1 只单身雄性。接下来，将单身雄性释放到没有虫子的茎上，并将同一只雌性释放到那里。比较了它们之间的求爱行为序列。该实验对 41 对男性和女性进行了重复，其中大约一半（20 例）的实验是以相反的顺序进行的。雄性在求爱中是主动的，而雌性要么接受求爱，要么逃避求爱。与单独求爱时（22%）相比，当雄性在集体求爱时（73%），雌性接受求爱的概率更高。这是因为，如果雌性发现雄性附近存在其他昆虫，雌性逃离雄性的行为就会减少。结论是，女性的选择是男性群居性的选择力量。
Adults of a stink bug, Megacopta punctissimum, from mating aggregations on their host plants, based on the gregarious habit of males. A female was released on a stem on which there was an aggregation of 2 mating pairs and 1 bachelor male. Next, the bachelor male was released on a stem on which no bugs were present, and the same female was released there. Sequences of courtship behavior were compared between them. This experiments was repeated for 41 pairs of males and females, and about half (20 cases) of these experiments were made in the reverse order. Males were the active sex in courtship, whilst females either accepted the courtship, or escaped from courting males. Females accepted courtship with a higher probability when male courted in aggregations (73%) compared to solitary conditions (22%). This was because the escape behavior of females from the males was reduced if females detected the presence of other bugs near the males. It was concluded that female choice is a selective force for gregariousness in males.
