In some firefly species, which sex is sometimes wingless?

Explanation:
Sexual dimorphism in fireflies includes cases where the female remains wingless as an adult. In these species, the female is larviform and stationary, often perched on vegetation and emitting light to attract flying males. Meanwhile, the males develop full wings and are capable of flight to seek out these signaling females. A classic example is the glow-worm Lampyris noctiluca, where the female stays wingless while the male is winged and migrates to find her. This is why the correct answer is the female—the wingless condition is a documented form of female specialization in some firefly species.
