''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''.
The species' common name refers to the characteristic flight of the male, which flies in a J-shaped trajectory, lighting on the upswing.
