Nantucket Pine Tip Moth. Rhyacionia frustrana (Comstock). Adult


This insect attacks all species of "hard" pines, except slash and longleaf.

The moth lays its eggs singly on needles, buds, or shoots. Upon hatching, the larva feeds at the base of a shoot or bud. Feeding sites are usually marked by exuding pitch and frass. The growing larva tunnels into the bud or shoot tip and pupates. From one to four generations per year may occur, depending upon climate limitations.
