What caused the horizontal split in this maple tree?
Answer
If you’ve been following our This Week in the Woods feature, you may recognize this cut-like scar as the work of a sugar maple borer larva. This common long-horned wood boring beetle spends two years in the tree, emerging as a bright yellow and black beetle. Learn more about this beetle – and the damage it may cause – from this U.S. Forest Service report.
