So the answer to that question is, of course, it depends. And there's lots of variations. There's at least 23 species of fireflies in Ontario. Most of them glow at night because they're nocturnal, and that's usually the males that are involved in mating. Males are glowing and pulsing and flashing lights in a sequence that is very species-specific so that females can identify them as from the same species.
That way there's no missed mating or wasted energy trying to court a female that's not in your species. A few species are diurnal in the daytime and so they don't usually glow, although most glow worms as they call them in Europe , or lightning bugs as we call them here, during one of the maturation stages do glow.
It even can be the caterpillars or the larvae of the firefly that glow. These aren't city beetles; you're likely to see lightning bugs in parks, yards, gardens, meadows and woodland edges. Fields and gardens give lightning bugs the long grass they love. During the day, when they're not so active, they'll hang out on the ground.
Tall grass provides cover during the daylight hours, as well as a good vantage point for sending and receiving signals at night. As the sun sets, they'll make their way to the tips of grass blades, where they'll launch from to begin their night's work. Night time is time for romance in the lightning bug world. Their bioluminescence helps in that department.
Each species has its own light flashing pattern, which helps them to attract mates of the same species. Of course, if you're like most people, you'd rather simply wait for dusk when they come to life and shine their lights for all to see!

Feeling crafty? Did you know you can make a simple homemade lantern by catching fireflies and putting them in a clear glass jar? Instead of possibly harming fireflies, though, you can make something similar with a few glow sticks and some glitter.
Firefly research is a great excuse to head outdoors after dark to explore and have fun. The Museum of Science's Firefly Watch activity gives aspiring entomologists an opportunity to conduct all sorts of backyard research on nature's night lights.
