本文研究了群居交配的瓢虫（Colpula lativentris）雌雄个体获得配偶概率的空间关系与聚集大小的关系。操作性别比总是强烈地偏向于男性。雌虫获得配偶的概率相对稳定，且与群体大小无关，为理想的自由分布。此外，室内实验表明，多次交配和饲养密度对雌性繁殖力的影响很小，表明雌性在繁殖成功方面的理想自由分布。另一方面，在更大的群体中，雄性获得配偶的可能性更高，那里有更多的雌性可供选择。这种来自理想自由分布的男性差异与感知约束下的理想自由分布所预测的模式相似（亚伯拉罕，1986），但与不平等竞争能力下的模式不同。
Spatial relationships of mate acquisition probability for individuals of both sexes of a gregariously-mating coreid bug,Colpula lativentris, were studied in relation to aggregation size. Operational sex ratio was always strongly male biased. Mate acquisition probability of females was rather constant and independent of aggregation size, as predicted by an ideal free distribution. Moreover laboratory experiments showed that both multiple mating and rearing density little affected female fecundity, suggesting ideal free distribution of females in terms of reproductive success. On the other hand, mate acquisition probability of males was higher in larger aggregations, where more receptive females were available. This male discrepancy from an ideal free distribution was similar to the patterns predicted by an ideal free distribution under perceptual constraints (Abrahams, 1986), but not by that under unequal competitive ability.
