I believe that I can solve the energy shortage in our insect world. I am Professor Firefly. I can produce light in my abdomen. I can make the dark night become bright. It is a good opportunity for me to conduct a lecture to explain my invention. I have a special light organ on the underside of my abdomen. When I take a breath, the oxygen rush into my abdominal trachea and a chain of chemical reactions will be took place and light will be produced. However, the light is cold because it produces no heat. I use the light for attracting mates. I also create flashing light to warn the predators that I am taste bad. However, frogs eat a lot of my family members and I hate frogs. I will try my best to invent a laser gun in my body to kill them.
