They are mysterious, elusive, almost magical; when twilight descends, these little creatures suddenly make their presence known as they fly lazily in the hot summer air, flickering and twinkling like miniature shooting stars that seem to be within reach. Fireflies (Lampyridae) prefer to live in moist environments, which is why many cherish childhood memories of trying to catch them while camping in forested areas or spending time near Canada's many lakes and rivers. Their luminescence is an object of fascination—an effect that has been recreated on this beautifully coloured coin using glow-in-the-dark technology!
While not every firefly flashes, they are the only insects that are capable of flashing distinct patterns as a method of communication to attract a mate, or as a warning to predators. Fireflies are also bioluminescent as larvae, although they are rarely seen at any other time than in their adult stage; it is then that their appearance on a summer night adds a spellbinding quality to the beauty of Canada's great outdoors.
In the natural world, the firefly's bioluminescence is generated by dedicated light organs that are located under their abdomens; there, two chemicals called luciferin and luciferase mix with oxygen, magnesium and adenosine triphosphate (ATP) to emit the glow that gave the insect its name.
