After pupation is complete, the adult moths emerge and begin searching for mates. Females tend to move less than males, and both sexes prefer scuttling over surfaces to flying— some adults never fly at all. Adults can live for an additional 15–30 days, after which they die (otherwise death takes place shortly after mating for males and shortly after egg laying for females). Life cycle may be completed within one month under the most favorable conditions ( and 70-75% relative humidity) but may take several years (lower temperatures and humidity will only slow development, larvae will still hatch and grow at temperatures as low as and can survive up to ).
