Common eastern firefly

Photinus pyralis

''Photinus pyralis'', known by the common names common eastern firefly and big dipper firefly, is the most common species of firefly in North America. This organism is sometimes incorrectly classified as ''Photuris pyralis'', which likely results from mistaking the similar sounding genus ''Photuris''.

Behavior

Males of ''Photinus pyralis'' locate females by a series of light flashes, to which females respond with a coded delay flash. The ''Photuris'' female may also lure a ''Photinus pyralis'' to be eaten to obtain spider-repellent steroids which Cornell researchers named "lucibufagins" in 1997.
