Bronze Birch Borer larvae are best described as which of the following?

• A. Creamy white, with flattened segments and flat heads
• B. Dark brown, cylindrical with hard plates
• C. Green and leaf-like
• D. White with waxy filaments

Answer: (A)

Bronze birch borer larvae are flatheaded borers, so they have a creamy white, legless body with flattened segments and a flat, broad head capsule at the front. This combination of color and a distinctly flattened body shape is characteristic of this group, setting them apart from other larval forms. They live beneath the bark and feed in the cambial region, which is why you’d see smooth, grub-like larvae under the bark rather than dark, cylindrical, leaf-like, or waxy-looking insects. The description given matches the typical appearance of these larvae and is the best way to identify them.
