Which statement about Sphingidae adults is described in the notes?

• A. Pointy horn on rear end
• B. Rest with thorax tilted up and head tilted down
• C. Big wingspan can be 16 cm
• D. Black geometric patterns on wings

Answer: (C)

Sphingidae adults are notable for their large size, and the notes highlight a substantial wingspan as a defining feature. Some hawk moths reach about 16 cm across from wingtip to wingtip, which stands out as a widely documented trait across the family. This broad wingspan is a clear, consistent characteristic described in basic notes and helps distinguish Sphingidae from many other moths.

Other details—such as having a pointed horn at the rear or a particular resting posture—can vary among species within the family. Not all hawk moths wear a prominent horn, and resting positions can differ, so those traits aren’t as universally reliable a descriptor in general notes.
