Conducting and reporting the study along with Eisner, who is a member of the National Academy of Sciences, were Michael A. Goetz, a postdoctoral fellow in chemistry at the time of the research; David E. Hill, postdoctoral fellow in neurobiology and behavior at the time; Scott R. Smedley, postdoctoral fellow in neurobiology and behavior; and Jerrold Meinwald, the Goldwin Smith Professor of Chemistry at Cornell and also a member of the National Academy of Sciences. Female Photuris fireflies can imitate the Photinus delay-and-flash signal, and they use it to their chemical advantage. Instead, these dark fireflies use airborne smells, such as pheromones, to communicate. Hadley, Debbie. They pounce, they bite, they suck blood all the gory stuff, Dr. Lewis said.

And the spiders' response to lucibufagin also was tested with fruit flies (Drosophila melanogaster). Though closely related to the nocturnal, lantern-bearing Big Dippers, members of this genus, Ellychnia, dont light up at all, probably relying on pheromones alone to find mates. When fruit flies were treated in the laboratory with lucibufagin, spiders either left the fruit flies alone or only tasted them. Some species of fireflies feed on other firefliesmost notable is the The female finds a plant stalk to climb. Cheyenne McKinley is a senior biology major at Bucknell University. Both male and female fireflies use bioluminescence (biological light) to attract mates. Although they can easily spot fireflies by their glow, they rarely eat them. Photuris females enjoy munching on males of other genera. Wthout lucibufagans from a Photinus firefly, the Photuris firefly is attacked and eaten by a Phidippus jumping spider, A Photuris firefly with lucibufagans can repel the spider. signal it with a flash of her own.
