![]() When the eggs hatch 7 to 10 days later, small yellow larvae that darken rapidly emerge. The list of recorded hosts includes Carya (including Carya illinoensis), Juglans cinerea, Liquidambar styraciflua, Diospyros virginiana, Rhus, Gossypium, and others. Larvae are solitary in later stages and rarely occur in numbers large enough to cause defoliation however, an individual larva can strip several branches of their leaves during the ravenous fifth instar. There are regional preferences, with the utilization of sweet gum and persimmon in the south, and sumacs where the others are not available. They are laid either singly or in groups of up to four on the upper surface of the host plant leaves, favoring nut trees such as Juglans and Carya (walnuts and hickories). Its eggs are yellowish, oval and 2 mm in diameter. It burrows into the ground to pupate in an earthen chamber, rather than spinning a cocoon. The life cycle of the moth is typical of the Saturniidae species, and typical of the Ceratocampinae. The adult moth is the largest moth by mass in latitudes north of Mexico, as are the spectacular larva and the substantial pupa. The species was first described by Johan Christian Fabricius in 1793. The caterpillars are called hickory horned devils. See more information about root2shoot.Citheronia regalis, the regal moth or royal walnut moth, is a North American moth in the family Saturniidae.

Note that it is wearing a bright yellow plush fur jacket with hot pink sleeves! The extra warmth provided by the jacket serves to insulate the moth’s flight muscles, as the evenings are still quite cool. The Rosy Maple adult moth, however, is quite beautiful. They can be periodically and locally quite destructive as they munch through maple leaves. ![]() The eggs were laid on maple leaves in batches of 10 to 20 and when they hatch, the little caterpillars will all stick together, until they go off on their own and disperse, as they seek fresh maple foliage. They were done with egg laying by the time the next sun rose and became bird and ant food. Then at sunset, they flew away to lay their eggs. All through the day, the females stayed inactive. By the next morning, the fertilized females were resting, while the sperms deposited in them by the males made their way into the eggs inside the females. Late into the night, throughout the Catskills forest, they mixed and mated. They had spent the winter in the ground in their pupal stage, changing from a caterpillar to a moth. Over several late afternoons, the local populations of this moth emerged en masse. The majority of them were dead within three days of emergence. This week millions of Rosy Maple Moths, ( Dryocampa rubicunda) emerged as adults. This was the week of the Rosy Maple Moth. ![]() Many emerge as adults and complete their life cycle in a week. Throughout our gardening season, different plants flower and fruit at their own particular time. The fly fisherman knows that different fly patterns are effective at different times of the season. The local cast of characters changes throughout the season. ![]()
