Damage by these insects is confined to the leaves of birches. Birch leafminer larvae make blotch mines which eventually give leaves a brown, wrinkled appearance. Inner leaf tissue may not be completely destroyed by the Birch leafminer.
Note the appearance of black frass in mines. Management: Damage tends to be more serious on open-growing ornamental birches than on trees in forest stands.
Native to Europe, the birch leafminer, Fenusa pusilla, first appeared in Connecticut in This pest is known to feed on most species of birch trees, although susceptibility varies. The birch leafminer feeds on the tissue between the upper and lower surfaces of newly emerging leaves producing large dead blotches and eventual leaf loss.
Leafminer's Habitat. Leafminers can be found throughout the United States, although they are not as ruinous in the northern states. Leafminers may inhabit a variety of plants and trees, including spinach, kale, peppers, tomatoes, pumpkins and squash plants, as well as cottonwood, birch, aspen and Ponderosa pine trees.
