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.

The aim of this website is to provide information about many species of moths and butterflies around the world, with a slight focus on rearing them in captivity.
