Tufts researchers shine light on firefly mysteries

ity have led to the evolution of chemicals produced by their reproductive glands. These chemicals kill the sperm of other males that have mated with the same female but they are also toxic to the female -- hence conflict."

In a collaborative research effort with insect physiologist and Tufts postdoctoral research fellow Dr. William Woods, Lewis is also examining other questions, such as how much energy the males' "flashy" courtship displays require--an effort that will involve laboratory testing in tiny respirometry chambers to measure the carbon dioxide produced during flashing and resting.
