Which statement about Bronze Birch Borer adults is true?

• A. They are slim and tapered at the end with metallic wing covers.
• B. They are round with bright orange wing covers.
• C. They are large and dull brown with striped elytra.
• D. They are wingless.

Answer: (A)

Bronze Birch Borer adults are slender beetles with a tapered end and a metallic sheen on their wing covers. They’re small, about a quarter inch long, and their shape is elongated rather than round, with smooth, metallic bronze to greenish elytra. This fits the true appearance much better than descriptions of a round body with orange wing covers, a large dull brown body with striped elytra, or a wingless form. So the statement that they are slim and tapered at the end with metallic wing covers is the correct description of these adults.
