    Regal Moth - (Citheronia regalis)

    The striking patterns on the large Regal Moth make it easier to spot on the walnut and hickory trees it visits.




    Staff Writer (7/21/2017): Both striped and spotted, the Regal Moth can also add "large" to the list of characteristics to identify it. The orange and blue-gray stripes run along the tops of the forewings with less prominent striping on the hind wings. The head and abdomen are hairy with white stripes down the back. Yellowish spots of various sizes dot the forewings. As a member of the Giant Silk Moth family, it can fill up the palm of the hand.

    This species of moth spends its summer nights searching for a mate. Eggs are laid on walnut, hickory, sweet gum, ash and sumac trees. Caterpillars eat the foliage of their host tree and cocoon in a shell made of earth, not silk. The distinct appearance of the caterpillar has given it the moniker 'hickory horned devil'. Its body is studded with reddish-orange horns that end in black tips. Its body can be a variety of colors depending on the individual: green, brown, bluish. Only one generation is produced every year regardless of region.
