Even though a firefly’s light is triggered by oxygen, fireflies do not have lungs.The fireflies that lose their ability to make light use scent to find mates instead. All fireflies are bioluminescent as larvae (which is why the larvae are often called glowworms), but not all of them shine as adults.They release a bitter defensive chemical when eaten, which helps to keep predators away. Fireflies taste horrible to predators like birds and mice.Don’t use mosquito-repelling chemicals in your garden, as these will also repel fireflies.Place bird baths in grassy areas or near shrubs fireflies will appreciate the water source.Fireflies like to hang out in grassy meadows, so if you want them to visit your property, let some parts of your lawn grow out or plant tall ornamental grasses. They enjoy perching on the tips of long blades of grass while searching for a mate.Fireflies appreciate shrubs and low trees for daytime shelter, so consider planting some to keep them around.The best way to attract these blinking bugs is to turn your yard or garden into the ideal firefly environment: Unfortunately, some common methods of deterring mosquitoes (like using a pesticide) also kill fireflies and are another reason for their decline. One downside to firefly watching is that mosquitoes also like the same conditions.

By comparison, a standard incandescent light bulb is less than 10 percent efficient, and an LED ranges between 40 and 50 percent efficient! How to Find Firefliesįireflies are most abundant in the eastern half of the continent, from Florida to southern Canada, but different species can be found anywhere in North America. This cold, living light is almost 100 percent efficient, losing only a fraction of its energy to heat.
The firefly regulates the flow of oxygen into its abdomen, which allows it to turn its taillight on and off. This light, the result of the chemical reaction of bioluminescence, occurs when two substances, luciferin and luciferase, react with one another when exposed to oxygen. Photocytes, or light cells, in the insect’s abdomen are where the glow is produced. Fireflies are often found in meadows or next to creeks, as they like damp areas. Fireflies even have an advantage over bees, because their warning can be seen in the dark!
In the same way that bees scream “Danger!” with their black and yellow stripes, fireflies show their toughness with their light. Carnivorous females of the genus Photuris are known to entomologists as “ femmes fatales.” These fireflies mimic the flashes of females of other firefly genera the unsuspecting courting male flies in (expecting romance) and is promptly eaten.Ī firefly’s light can also serve as a warning to predators. The brighter the female’s response, the more interest she has in the male.Įach species of firefly has its own unique flash that is characteristic of its sex and species.
If a female is impressed by a male’s flickering, she will flash back a response to the twilight glow. They try to flash very quickly, because this is what attracts females. The main purpose of a firefly’s light show is to attract a mate. The males fly around while turning their lights on and off, hoping to get the attention of a flightless female waiting in low vegetation.
