Which feature is characteristic of Cicadidae nymphs?

• A. Wings in nymphs
• B. Fossorial front legs in nymphs
• C. Bright coloration in nymphs
• D. No legs in nymphs

Answer: (B)

Cicadidae nymphs are specialized for life underground, and the defining feature is their fossorial forelegs. These front legs are broad, strong, and spade-like with robust claws, built for digging through soil to create tunnels and reach plant roots. This digging adaptation fits their long underground phase, where they feed on root xylem and stay hidden until they’re ready to molt into winged adults.

Wings in nymphs would not fit because cicada nymphs do not have wings until the final molt into adults. Bright coloration isn’t typical for these underground dwellers, since cryptic, earth-toned bodies help them blend with soil. And they do have legs—their forelegs are specifically adapted for digging rather than lack of limbs.
