Arctiidae is described as having which feature?

• A. Geometric patterns or spots
• B. Curved filiform antennae
• C. Hairy, prominent tufts on the back
• D. Colored wings

Answer: (B)

Morphological clues like antenna shape are a quick way to tell moth families. Arctiidae, the tiger moths, are often described as having curved threadlike antennas. Filiform means threadlike, and the curved aspect refers to a gentle bend along the antennae, which helps distinguish them from other groups that have straight, clubbed, or heavily feathered antennae. The other features listed—wing patterns, hairy tufts on the back, or colored wings—are common in many moths and aren’t as diagnostic for identifying Arctiidae specifically. So the curved filiform antennae best describe this group in this context.
