Elasmucha ferrugata (Fabricius, 1787) (Heteroptera: Acanthosomatidae) provides maternal care of eggs and larvae. Adults of both sexes have functional anterior dorsal abdominal scent glands (DAGs). Study of all internal and external cuticular structures of DAGs revealed that no DAGs are fully functional in the 1st larval instar, and very probably they are only slightly functional in the 2nd instar. Median and posterior DAGs are undoubtedly not functional in adults. There exists sexual dimorphism in the number of multicellular glandular units in anterior glands in adults. The occurrence of cuticular ductules of these units proves these to be functional glands. This is best considered in combination with the findings of a well-developed evaporatorium. Developed cuticular intima of the gland reservoir and/or the nearly closed ostiole or ostiolar scar bears no information about the functionality of the gland.
锈色棘缘蝽（Fabricius，1787年）（半翅目：棘缘蝽科）会对卵和幼虫进行亲代抚育。雌雄成虫都具有功能性的腹部前背侧气味腺（DAGs）。对DAGs所有内部和外部表皮结构的研究表明，第一龄幼虫期的DAGs没有完全发挥功能，很可能在第二龄幼虫期它们也只是稍有功能。成虫的中部和后部DAGs无疑没有功能。成虫前腺中多细胞腺单位的数量存在性别二态性。这些单位的表皮小管的存在证明它们是有功能的腺体。这最好结合一个发育良好的蒸发盘的研究结果来考虑。腺体储库发育良好的表皮内膜和/或几乎封闭的小孔或小孔疤痕并不能表明腺体的功能情况。
