There just might be hundreds of them. Maybe thousands. They hover, bob, and weave above the grass. They are not faery folk. They are fireflies. They effortlessly fly, their wings buzzing. But, the fluttering goes unseen in the dark, set against a ball of light that emanates from them. As children, we oogle them endlessly. Maybe it is the longing to dance among them. It may possibly be the desire to fly through the trees and explore the world around us. It could be the fascination with the glow. I used to watch them from the front porch of my house when I was younger. Even though I live in the city now, I can close my eyes and still see them across the street, in the late summer, hovering over the corn.
The firefly is an enchanting crepuscular beetle, which means that they are mostly active during the twilight. There are more than 2000 species that live in both temperate and tropical climates. Popular spots to find them are in places their little ones can easily find food, such as marshes or wet, wooded areas. Firefly larvae eat a range of goodies, including earthworms, snails, and slugs. As they get older, these radiant adults tend to sip on plant nectar. They use flashing patterns to communicate and to find a mate.
Also called “glow worms” or “lightning bugs”, they produce a green, red, or orange light with no ultraviolet or infrared rays. This is a “cold light” with no heat byproduct. The lower abdomen of a firefly contains special light-emitting organs. Luciferase, an enzyme, is a catalyst for oxidation when combined with adenosine triphosphate and Luciferins, a light-emitting pigment. 90 to 100% of the energy that a firefly gives off is transmitted as light. This contrasts with a incandescent light bulb, which emits only 30% of its energy as light.
If you have ever been duped, listen up. These femme fatales have cracked the code of some unsuspecting males. The females of some species of fireflies mimic the mating flashes of other species. When a male responds to the call, the female pounces and eats him. They even steal defensive chemicals from their prey, because they do not produce very much of it themselves. These aggressive gals are called photuris mimics.
To increase firefly activity on your property, let us put these tricks up your sleeve, so that you do not get duped yourself. Reduce or completely eliminate the amount of chemicals that you put on your lawn. Reduce any extra lighting in the area. Since fireflies use light signals to find a mate, you may not see as many buzzing about when the moon is full and the sky is clear. Provide fireflies a place to rest during the day with low, over-hanging trees, tall grasses, etc.
