Quadrina diazoma - the sole species in the Quadrina genus - occurs in the Southern USA (Arizona and New Mexico) and southwards into Mexico. The moths in this post are the offspring of a female caught near Mazatlan, so that's how far south they go for sure. The moths are on the wing in June/July. However, in captivity adults can start to emerge from April on. It all depends on the temperature (warm) and humidity (high) for them to eclose. The cocoons overwinter (yes, that is different from many other Lasiocampids occurring in this region, which more often overwinter as caterpillars). The wingspan is somewhere between five and seven and a half centimeter. Diazoma can be quite variable with a lighter or darker brown ground color. The moths in this post appear fairly light compared to some other pictures I've seen. The caterpillars will be in the next post.
