Birch Leafminer
Birch leafminers are sawflies, which are closely related to bees and wasps. They are among the most common insect pests affecting Birch trees (Betula spp.) in North America. Areas inside the leaves are consumed by the larvae affecting the leaves' ability to produce food. Yearly browning of birch leaves are noticed in mid July and August, but the leafminers have been feeding inside the leaf tissue since early spring.

Famous quotes containing the word birch:
“The birch stripped of its bark, or the charred stump where a tree has been burned down to be made into a canoe,—these are the only traces of man, a fabulous wild man to us. On either side, the primeval forest stretches away uninterrupted to Canada, or to the “South Sea”; to the white man a drear and howling wilderness, but to the Indian a home, adapted to his nature, and cheerful as the smile of the Great Spirit.”
—Henry David Thoreau (1817–1862)
