Pheromone glands are present in the abdominal sternites of the pregenital region in the male adults in all British species of Acanthosomatidae. Secretory units are most numerous in the hawthorn bugAcanthosoma haemorrhoidale and maternal bugElasmucha grisea, next most numerous in the birch bugElasmostethus interstinctus, and least numerous in the juniper bugCyphostethus tristriatus. The largest dorsal abdominal scent glands were found inCyphostetheus. Ordinary dermal glands are also present. They are most numerous along the lateral margins of the abdomen. It is possible that Pendergrast's organ is the source of a female-produced pheromone. Secretory units were numerous in this organ inC. tristriatus female adults.
信息素腺体存在于英国扁蝽科所有种雄性成虫的前生殖器腹侧板上。在悬铃木扁蝽 Acanthosoma haemorrhoidale 和榆绿毛萤叶甲 Elasmucha grisea 中，分泌单位数量最多，其次是桦扁蝽 Elasmostethus interstinctus，数量最少的是桧扁蝽 Cyphostethus tristriatus。最大的背侧腹部气味腺位于 Cyphostethus 中。也存在普通的皮腺。它们在腹部的侧缘数量最多。Pendergrast 氏器可能是雌性产生信息素的来源。在 C. tristriatus 雌成虫的这个器官中，分泌单位数量很多。
