Which venation feature is listed in the notes?

• A. Short 3rd anal vein
• B. Bright orange with black markings
• C. Front legs are short and clawless, not used for walking
• D. Larvae found on milkweed

Answer: (A)

Wing venation patterns are a key set of features used to distinguish insect groups. The third anal vein is one of the veins along the wing’s hind edge, and its length can vary among species. A short third anal vein describes a specific venation pattern that notes would use to identify and differentiate taxa. Since the question asks for a venation feature listed in the notes, this short third anal vein is the option that fits. The other statements describe coloration, leg morphology, or larval habitat—traits not related to wing venation.
