A New Look at Firefly Romance

Caption: This is a male Photinus firefly that failed to successfully transfer a spermatophore -- or nuptial gift -- during mating. The spermatophore is trailing from male reproductive tract. While a female's initial assessment of potential mates is based on males' luminescent flashes, research by Tufts University biologists reveals that once a pair makes contact, flashes no longer matter. Instead, it's those males that have larger nuptial gifts to give that win out with higher reproductive success.
