| Adults are about 25 mm long. The forewings of males and females are reddish to grayish brown with a wavy band of black and brown markings toward the wing tips. The hind wings are pale brownish gray and fringed on the trailing edges. |

Lesser peachtree borer (LPTB) larvae feed in the inner bark and cambium tissue of all stone fruits. (See larva.) Females primarily deposit eggs in wounded areas so problems are more severe in previously infested orchards or sites with a high incidence of canker, winter injury or mechanical damage. Larval feeding mainly causes a loss of production on injured limbs and tree death caused by trunk girdling.
There are two generations per year in Michigan. First-generation adults begin to emerge around shuck split or shuck fall in peach. The flight of second brood adults generally begins in July and continues into September.
