A typical Photinus is a "lightning-bug firefly" (as opposed to the so-called "glowworm firefly") because it emits light in its winged stage. Both male and female adults produce mating signals with an abdominal light organ or "lantern". Members of Photinus are called "rover fireflies" because typically males fly about singly, not in groups ...
A larviform female with light-emitting organs on her abdomen. Unlike actual larvae, she has compound eyes. Fireflies are beetles and in many aspects resemble other beetles at all stages of their life cycle, undergoing complete metamorphosis. [6] A few days after mating, a female lays her fertilized eggs on or just below the surface of the ground.
While these bugs aren’t bioluminescent, they are often mistaken for fireflies, the most famous light-emitting insects! Soldier beetles are known for their heads mimicking a firefly’s colors.
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 ]
Most light we know produces heat, but bioluminescence does not, making it a ‘cold light’. That means less than 20% of the light produced via bioluminescence generates thermal radiation (heat).
The term comes from the Greek γυνή (gynē) 'female', ἀνήρ (anēr) 'male', and μορφή (morphē) 'form', and is used mainly in the field of entomology. Gynandromorphism is most frequently recognized in organisms that have strong sexual dimorphism such as certain butterflies, spiders, and birds, but has been recognized in numerous ...

The light can be seen by males up to 45 metres away. The light is emitted continuously, although they will wave their abdomens from side to side, which gives the impression of it brightening and dimming. Larvae are sometimes seen to glow, although they seem able to turn off their light more easily than the female, especially when disturbed.
