Some species of fireflies feed on other firefliesmost notable is the genus photuris, which mimics female flashes of photinus, a closely related species, in order to attract and devour the males of that species. Scientists have developed remarkable uses for firefly luciferase, the enzyme that produces bioluminescence in fireflies. And plants are 'experts' at gleaning useful chemicals from microorganisms.
