females will oviposit anywhere from a few days to a month or longer after mating, depending on species, the age of the female, feeding, temperature, etc
Finally my acanthops erosula laid her ootheca after I increase the humid and temperature. Although I do not pretty sure if the pair mated successfully I would like to try with the incubation, any suggestion regarding to the humidity and temperature? How many days can take to born the nymphs? Should I move the ootheca oustide the terrarium to another case?
