Photinus pyralis, also known by the common names the common eastern firefly[3] or big dipper firefly,[4] and sometimes called a "lightning bug",[5] is a species of flying beetle. An organ on its abdomen is responsible for its light production.[6] It is the most common species of firefly in North America, and is typically found east of the Rocky Mountains. Photinus fireflies are often confused with fireflies of the similar-sounding genus, Photuris, which are also found in North America.

Common eastern firefly (Photinus pyralis)

These fireflies are most noticeable around twilight in the spring and summer months.[7] The common name, big dipper firefly, is due to the characteristic flight of the males, whose trajectory appears to follow a J-shape, lighting on the upswing.[3][8] During flight, this J-pattern is used alongside light flashing to attract females, who rest on vegetation and signal back to males if interested.[9] The firefly flashes are stimulated by light-activated proteins, not rhythmic impulses as originally thought.
