As predaceous insects, the Asopinae have a great economic importance. The knowledge about the development of the species is essential for use in biological control programs. However, only 1% of the Neotropical Asopinae species have the immature stages known. In this work we describe the egg and the five nymphal stages of Podisus graziae Brugnera, Roell & Lemaître, 2021 using light and scanning electron microscopy. The results show that P. graziae eggs and nymphs present unique characters which are not observed in other species of the genus and subfamily. As other Podisus species, the egg present long aero-mycropilar processes, however, the chorion and operculum have a ring of minute spine-like projections. As main diagnostic characters of nymphs, the iridescent coloration of head, thorax and abdominal plates, and a pair of yellow spots in the pronotum and anterior region of abdomen are noticed.
作为捕食性昆虫，姬蝽亚科具有重要的经济意义。了解该物种的发育情况对于生物防治计划的应用至关重要。然而，新热带姬蝽亚科中只有1%的物种其未成熟阶段是已知的。在这项工作中，我们使用光学显微镜和扫描电子显微镜描述了2021年由布鲁格纳、罗埃尔和勒迈特发现的格拉齐亚斯豆蝽的卵及五个若虫阶段。结果表明，格拉齐亚斯豆蝽的卵和若虫具有该属和亚科其他物种未观察到的独特特征。与其他豆蝽属物种一样，其卵具有长长的气微孔突，但卵壳和卵盖有一圈微小的刺状突起。作为若虫的主要诊断特征，可注意到头部、胸部和腹板的虹彩颜色，以及前胸和腹部前部的一对黄斑。
