据报道，一种盾虫和三种穴居昆虫(半翅目：五总科：副星虫科和天牛科：塞希里亚科)的子社会性涉及到为后代提供食物。我们提出了第一个关于洞穴昆虫变色小毒蛾的亚社会行为的报告，重点是母性关怀的表现，特别是营养卵的产生，后代的保护，以及逐步的供应。在我们的研究中，每只雌性产生一个卵块，其中包括一些营养卵。若虫孵化前，雌虫停留在巢中，并表现出卵块守卫行为。在若虫孵化几个小时后，母亲就开始提供食物。每一位母亲都用她的鼻子拖着一粒种子(比她的身体大)来到巢中，作为若虫的食物。这些发现表明，杂色斑潜蝇的母性照料行为与其他一些五足类物种的报告相似，营养产卵和提供巢是相互关联的进化过程。
Subsociality involving provisioning for offspring has been reported for one shield bug and three burrower bug species (Hemiptera: Pentatomoidea: Parastrachiidae and Cydnidae: Sehirinae). We present the first report of subsocial behaviour in the burrower bug Adomerus variegatus (Signoret), focusing on manifestations of maternal-care, specifically the production of trophic eggs, guarding of offspring, and progressive provisioning. In our study, each female produced an egg mass that included some trophic eggs. Prior to nymphal hatch, females remained in their nests and showed egg mass guarding behaviour. Mothers started provisioning behaviour a few hours after nymphal hatch. Each mother dragged a seed (larger than her body) with her proboscis to the nest as food for the nymphs. These findings suggest that A. variegatus shows maternal-care behaviours similar to those reported in some other pentatomoid species and that trophic egg production and nest provisioning have evolved as interrelated processes.
