Caption: These male fireflies give a nuptial gift -- sperm wrapped in a nutritious, high-protein package -- to females during mating. New research led by Tufts University biologists shows that some fireflies have evolved to have wingless females, and their males forego gift-giving to these "stay-at-home" mates.
