Basswood Leafminer

BYGL readers should be familiar with the Basswood Leafminer. We've reported on the skeletonizing and leafmining activities of this native beetle on its namesake host, American basswood for years. High populations cause entire basswood trees to become reddish-brown. Travelers on the northern portion of I-75 in Ohio will soon be treated to "flaming" basswoods gracing the woodlots along the route.
