In this study, we present for the first time information on nesting site, the architecture of nests, sex ration, and development of Centris (Trachina) perforator. Furthermore, we revised the literature and summarized the information on the nest biology of ground-nesting species of Centris. The nest of C. perforator consists of a main short tunnel that is split into branches with 2 to 15 brood cells. Females needed approximately one day for the construction and provision of each brood cell. This species is protandric with adults emerging between 48‒83 days. The nest of C. perforator follows the same pattern found in other species of the subgenus Trachina.

Centris (Trachina) 穿孔虫的生物学记录，并与该属 (Apidae: Centridini) 具有地面筑巢习性的物种进行比较分析

在这项研究中，我们首次提供了有关筑巢地点、巢穴结构、性别比例和 Centris (Trachina) 穿孔器发育的信息。此外，我们对文献进行了修订，总结了有关 Centris 地面筑巢物种的巢生物学信息。C. perforator 的巢由一个主要的短隧道组成，该隧道被分成带有 2 到 15 个育雏细胞的分支。雌性需要大约一天的时间来构建和提供每个育雏室。该物种是长期繁殖的，成虫在 48-83 天之间出现。C. perforator 的巢穴遵循在 Trachina 亚属的其他物种中发现的相同模式。
