The praying mantis genus Hierodula is widespread throughout temperate and tropical Asia, and its species are well recognised due to their large size. Nevertheless, the life history of many of its species remains unknown. Therefore, we investigate the biology, life cycle, mating, cannibalism, and spermatophore feeding of the species Hierodula tenuidentata. The mean incubation period of five field-collected oothecae was 36.4 days (± 0.5 SD) and thus very similar to oothecae laid in the laboratory (35.1 days ± 3.0 SD). The mean number of nymphs hatching from the field-collected oothecae was 22.0 (± 3.1 SD), while this number was considerably higher for the oothecae laid in the laboratory (97.1 ± 11.0 SD). The time needed from hatching to imago was about 89.1 days (± 0.7) and included nine moults for males and ten moults for females. The mean life span of females (93.3 days ± 5.3 SD) was longer than of males (48.6 ± 4.7 SD). We observed spermatophore feeding by the female at the end of mating; sexual cannibalism occurred during copulation.

螳螂属Hierodula广泛分布于亚洲温带和热带地区，其物种因体型庞大而广为人知。然而，它的许多物种的生活史仍然未知。因此，我们研究了细齿海藻的生物学、生命周期、交配、同类相食和精囊摄食。. 五个现场采集的卵囊的平均潜伏期为 36.4 天 (± 0.5 SD)，因此与实验室中放置的卵囊非常相似 (35.1 天 ± 3.0 SD)。从田间采集的卵囊中孵化的若虫平均数量为 22.0 (± 3.1 SD)，而实验室铺设的卵囊的这一数字要高得多 (97.1 ± 11.0 SD)。从孵化到成虫所需的时间约为 89.1 天 (± 0.7)，包括雄性 9 次换羽和雌性 10 次换羽。女性的平均寿命（93.3 天 ± 5.3 SD）长于男性（48.6 ± 4.7 SD）。我们观察到雌性在交配结束时喂食精囊；在交配期间发生性食人现象。
