Glenstone is host to a few species of native great silk moths (family Saturniidae) including the smallest silk moth, Dryocampa rubicunda, commonly called the rosy maple moth—whose wingspan ranges from one and a quarter to two inches. Like other saturniids, rosy maple moths have stout bodies covered in hair-like scales and are equipped with a set of feathery antennae. Adult rosy maple moths emerge from their pupae from mid-May through mid-July with the sole intention of mating and laying eggs. These moths are a striking combination of bright pink and yellow—signaling to predators that they are not a desirable meal—and are seen most often from late afternoon to late evening.
