Paradirphia fumosa, or the Smoky Emperor Moth, is a rare species of Saturiidae, that is endemic to Mexico – where they are reportedly found in the provinces of Sinaloa and Durango. Here, the insect is found on a higher altitude in mountainous environments; the parental generation of the insects pictures on this page was reportedly found on an altitude of 2000 metres.
Most notably, these small Saturniidae are diurnal (day-flying); the males become active during noon (in captivity around 14:00-15:00) especially when they are motivated by a little bit of warmth and sunlight.
Most unique is the habitat; reportedly, it is frequently shrouded by a thick mist in the early morning, which creates an atmosphere of extremely high humidity – only for it to evaporate when when the sun rises and warms the environment up, causing a natural cycle of very humid cold nights and mornings into naturally hot and dry daylight hours. Thus, one can imagine that in captivity, the insects appreciate being very well-ventilated and dry most of the time, but also with frequent cold mistings of water.
