1/8/2021: Monogamy of the cockroaches

While taking some colony pictures for a trade I noticed a tiny comedy unfold. Her face buried in a rotting apple piece, an adult female Therea regularis was flicking her rear legs at a curious male, preventing his advancements. I pondered this for a moment and recalled in the book Cockroaches: Behavior, Ecology, and Natural History, it is mentioned that in the related Therea petiveriana there is strict monogamy. Not that any sort of pair bond or relationship is formed, but insomuch that adult females will only reproduce once with one male in their entire adult lives. I wonder if this observation holds true for regularis as well.
