Native to North America, the oblique banded leafroller is not considered a major agricultural pest in the Untited States, in spite of afflicting a wide variety of woody host plants. Foliage damage from larval feeding is usually minor, and fruit damage superficial. 
Many of our most important shade and fruit trees can be afflicted: ash (Fraxinus), basswood (Tilia), birch (Betulaceae), buckeye (Aesculus), elm (Ulmus), ; holly (Ilex), maple (Acer), oak (Quercus), willows and poplar (Salicaceae), and especially those in the Rose family (apples, cherries, plum, hawthorn), pear, mountain-ash, and whitebeam.
There are two generations per year in all but the northernmost parts of its range, where adults appear in late June to July. Eggs are laid in clusters of 200-900 and covered with a waxy coating by the female. Larvae hatch in 5-12 days and either crawl to a protected location on its own tree or balloons, via a strand of silk, to another host.
Larvae are yellow-green, 25-30mm long, with a brown or black head. Later instars construct tubular shelters by rolling and tying leaves with silk; they may overwinter in the tube and complete their pupal stage in late May or early June. Pupation takes 10-12 days. 
Order Lepidoptera: Moths. Unlike the butterflies, moths are usually nocturnal. Many moths and their caterpillars are major agricultural pests in large parts of the world. Moths in the family Tineidae are commonly regarded as pests because their larvae eat fabrics, clothes and blankets made from natural fibers such as wool or silk. Moths in the genus Farinalis feed on stored grain, flour, corn meal and other milled grain products.
