Which wingspan is listed for Pyralidae?

Large (3-15 cm) Small heads, hairy Dark eyespots, hair like scales 0.75-1.5 inch wingspan

Correct Answer:

0.75-1.5 inch wingspan

Explanation:

Wingspan is the standard size descriptor for moths, and Pyralidae moths are typically small to medium in size. A wingspan of about three-quarters to one and a half inches (roughly 2 to 4 cm) fits that common range, so this option matches the usual measurement used for this family. The other choices either suggest a much larger wingspan or describe features such as head shape or color patterns, which aren’t about size. Therefore, the listed wingspan for Pyralidae is 0.75–1.5 inches.
