研究人员对现场收集的 229 个天疱疮社会性蚜虫 Colophina arma 群体进行了检查，了解其种群动态、繁殖时间表以及与士兵生产相关的生态因素，该蚜虫在第一龄期具有士兵种姓。 7 月菌落规模较小，8 月及以后逐渐变大；这种变化可能反映了寄主植物铁线莲的开花物候。士兵既不生长也不繁殖，但专门用于群体防御，在整个季节都会被发现。有翅的有性生殖，迁移到锯缘榉树上并产生有性世代，出现在九月下旬。侏儒一龄若虫在十月份产生，它们持续在 C. stans 上进行冬眠。统计分析表明，C. arma群体中士兵的比例可能与无翅成虫的比例、群体规模和季节变化有关。有性生殖和侏儒若虫仅在秋季产生，这反映了这些变体的越冬作用，并表明这些变体的产生可能受到与季节相关的环境因素的影响，例如短光周期和低温。
Field-collected 229 colonies of a pemphigine social aphid Colophina arma, which has a soldier caste in the first instar, were examined for its population dynamics, reproductive schedule, and ecological factors related tosoldier production. Colony size was small in July and became larger in August and on; this change probably reflects the flowering phenology of the host plant Clematis stans. Soldiers, which neither grow nor reproduce but are specialized for colony defense, were found throughout the seasons. Winged sexuparae, which migrate to Zelkova serrata and produce the sexual generation, appeared in late September. Midget first instar nymphs, which persist on C. stans for hibernation, were produced in October. Statistical analyses suggested that soldier proportion in colonies of C. arma might be related to the proportions of unwinged adults, colony size, and seasonal change. Sexuparae and midget nymphs were produced only in autumn, which reflects the overwintering roles of these morphs, and suggests that production of these morphs might be influenced by environmental factors related to the season, such as short photoperiod and low temperature.
