Which order features transparent wings with forewings larger than hindwings, three tail filaments, and adults that typically do not feed?

• A. Ephemeroptera
• B. Aeshnidae
• C. Libellulidae
• D. Coenagrionidae

Answer: (A)

This item hinges on recognizing a mayfly’s distinctive combination of wing form, tail filaments, and adult feeding habit. Mayflies have delicate, transparent wings with the forewings typically larger than the hindwings, giving a characteristic look when they are at rest. They also bear three long tail filaments extending from the abdomen. Adult mayflies generally do not feed because their mouthparts are reduced, and their brief adult life is focused on reproduction. This combination of wing arrangement, three tail filaments, and nonfeeding adults sets Ephemeroptera apart from dragonflies and damselflies, which have different wing relationships and do feed as adults.
