Numbers
Eighty-one decribed species are known from America north of Mexico.
Size
Forewing lengths from 2.5-4.5 mm.(1)
Identification
Adult - tiny moths with slender forewings that are held against the body at rest and taper to a rounded point; ground color of forewing orangish in many species but ranges from white through yellow and reddish to brown; often patterned with a thin white basal streak and several white wedges along costa and inner margin that point inward to middle of wing; hindwing reduced to a sharp lance-like midrib from which projects a wide fringe of hair-like scales (see wing illustrations of 49 European species)

Larva - tiny, grub-like, usually whitish or yellow with no markings.

Ova - generally eggs are flat, approximately 0.3 mm in length, 0.2 mm in width, and are lightly cemented to the lower leaf surface.(2)
Range
Much of North America and Eurasia.
Habitat
Various trees and shrubs.
Season
Adults may be present from March to November; individual species often have reduced flight seasons.
Food
Larvae mine the leaves of a wide variety of trees and shrubs but individual species are usually host-specific.
Life Cycle
All species' larvae are believed to possess three early sap-feeding and two later tissue-feeding instars. Sap-feeding instars initiate a slender, serpentine to wedgeshaped, subepidermal tract on the underside of the leaf. The succeeding two instars continue feed in the spongy parenchyma, which, by the third instar, is enlarged to form a blotch (2). Usually two or three generations per year.
