Females of a pinyon pine bark beetle,Ips hoppingi Lanier, were less attracted by the aggregation pheromone produced by conspecific males than by the pheromone produced by the neighboring sibling species,I. confusus (LeConte). Cross-attraction was elicited by males infesting the regional pinyon pine hosts (P. discolor andP. edulis) of eitherIps species in south-eastern Arizona. Pheromonal specificity has not accompanied speciation in this species pair.
白杨扁叶蜂雌性个体对同种雄性产生的聚集信息素的吸引力小于对相邻亲缘种——白杨多毛叶蜂（I. confusus (LeConte)）产生的信息素的吸引力。在亚利桑那州东南部，雄性白杨扁叶蜂以这两个白杨扁叶蜂物种的区域寄主（P. discolor 和 P. edulis）为食，从而引发了交叉吸引。在这个种对中，信息素的特异性并没有伴随着物种形成。
