A00E8794CC18FFCDFF0B179BB3BBFE02.taxon	biology_ecology	Notes on biology: the eggs are arranged horizontally and apparently do not have a clear design or pattern of organization in the position of the egg masses within the colonies. Each egg mass is covered by several layers of silk, the margins are flush with the substrate and the mass is closed until the nymphs hatch, thus, when there is more than one egg mass they are distinctly separated. The developmental time of Biguembia flavibrunnea n. sp. (Table 3) was among 261 and 283 days, between egg laying and adult emergence. In the adult stage, males lived up to five days, while females 76 – 88 days, thus, the total development time for males was between 266 and 288 days, while for females it was 337 – 371 days.	en	Andrade, Bruna Santos, Szumik, Claudia, Juárez, María Laura, Krolow, Tiago Kütter (2023): Revisiting Biguembia Szumik, 1997 (Embioptera: Archembiidae): New species, phylogeny and natural history.
