What is a Lightning Bug or a Firefly?

Fireflies or lightning bugs are light-emitting insects (beetles) that belong to the Lampyridae. While we only know about one firefly, the Lampyridae covers almost 2,000 lightning bug species worldwide, mainly in Asia, Central and South America, and parts of Europe.

They like moist and warm areas like open forests and fields close to streams or rivers. You may often spot them flying around the garden with water features or the fields at night.

Moreover, these bugs are famous for their bioluminescence lights emitted from the lower abdomen. But, the question is, “how is it possible?”. So, fireflies have an enzyme called luciferase.

With the presence of oxygen and ATP, this enzyme will react with a chemical compound called luciferin and produce a greenish-yellow glow.

Very interesting, huh?

Another fact is that the light is used by fireflies for mating. The males will emit a series of their bioluminescence light to attract the female lightning bugs. Then, the females will decide which flash of light is the most unique among the males. That’s where they started their courtship.

Apart from being nocturnal insects, the above scheme also explains why they like to scatter at night compared to the daytime. The daylight is their time to rest on the tall grasses.

Unfortunately, this mating process is significantly disrupted due to light pollution, which directly impacts the fireflies’ population.

Luckily, you can still try to invite them to your garden. Although it can’t be as much as when the bugs’ habitat is still well maintained, at least your efforts can conserve them and hopefully increase their population.

Alright, let’s move on to the next section!

What Plants Attract Lightning Bugs or Fireflies?

You must first understand their habitat before talking about how to attract more lightning bugs to your yard. As we previously discussed, they love to stay in humid areas with warm weather.

In addition to that, these light-emitting insects prefer some plants to live on and spawn, such as:

Tall grasses, for example: Indian Grass (Sorghastrum nutans), Eastern Gamagrass (Tripsacum dactyloides), and Broadleaf Uniola (Chasmanthium latifolium)
Dense Shrubs, such as Button Bush (Cephalanthus occidentalis) or Elderberries (Sambucus sp.)
Trees, such as Oaks (Quercus sp.), Elm Trees (Ulmus sp.), Dogwood (Cornus drummondii), Ash Trees (Fraxinus sp.) and many more.

These plants offer shade to these nocturnal insects to hide from sunlight exposure. Hence, they can rest peacefully to return to their night routine (hunting and mating!).

In addition, the tall, native plants also serve as an airstrip for fireflies and generally a habitat for their prey, like slugs and snails. Also, the fruit and flower-bearing one’s produce nectars and pollens they can feast on.

How to Attract Fireflies or Lightning Bugs to Your Garden?

Now, we are going to spill some exciting information about how to attract lightning bugs to your garden. In addition, the effort to invite them is also expected to help to increase their very declining population in their natural habitat.

So, what kind of preparation to ensure they linger around longer? Check them out below!

1. Provide Food and Habitat

The key to successfully attracting fireflies to your garden is providing proper habitat. As you know, lightning bugs thrive in damp, humid areas with warm or hot temperatures.

To achieve such conditions, leave the grass to grow tall and avoid excessive pruning of other native plants. Dense grass provides shelter to the bugs from sunlight during the daytime, while they will be mating and breeding at night.

How about the food? The larvae will eat several types of insects, such as snails, worms, and slugs. Meanwhile, the adults tend to feed on nectar and pollen. Some of them even eat each other of the same species.

Generally, this demeanor belongs to the females of Photuris fireflies and the males.

They will imitate the flash tones of the males from behind the tall grass to draw their attention. The males who expect the mating process will be surprised by the female predators ready to devour them. This behavior is known as femme fatale fireflies.

2. Offer Water Features

Adding water features to your garden will be the best choice to support preferable damp sites of the fireflies’ habitat. You can install something like a mini fountain, a pond, or even make container garden water.

Place them near plants that invite fireflies to visit, such as shrubs, tall grass, or native pine trees.

However, water accents in the garden can also invite unwanted insects, which are often a problem in the summer garden, the mosquitoes! They love to lay their eggs on the puddle water, which will hatch into mosquitoes that also may carry diseases.

If you have a pond, keep some fish that will prey on the eggs and mosquito larvae in the water. In addition, grow mosquito repellent plants, like lavender, catnip, marigolds, and lemongrass, around your water features to help reduce their population.

3. Native Trees are The Best!

Although it looks trivial, the presence of native trees can invite more fireflies to your yard. These trees are preferable to truly imitate fireflies’ natural habitat, given that each region or country has different species of fireflies.

In addition, fireflies tend to breed and lay eggs in humid areas, such as forests, where the dense native trees grow abundantly.

Moreover, the thick foliage offers shade to the surrounding so that the male fireflies can easily attract the attention of the females with their flash pattern, leading to matting.

Hence, growing those trees in your yard will increase the chances of increasing their population in the wild.

Some native trees that are lightning bugs you can try planting are bur oak, green ash, dogwood, golden ball lead tree, hackberry, and desert willow. Choose one of them and adjust it to the area where you live.

4. Protect The Females with Tall Ornamental Plants

Apart from being a comfortable place to live for fireflies, tall grass also provides a safe place for the females to lay their eggs. They also serve as a runway for the males, while the females prefer to hide under the blades.

In addition, they offer shades that make it easier for the males to flash their light, attracting the females to mating.

However, this type of grass often causes various problems, such as the emergence of pests. Generally, mosquitoes, ticks, and fleas love thick grass to hide. Therefore, people choose to prune the grass whenever they get dense.

As an alternative, you can try planting tall ornamental, like silver grass and fountain grass. In addition, the cotton bush and elderberries may offer additional garden ornaments that will attract fireflies and birds.

5. Turn The Garden Lamps Off!

Together with the massive development of urban areas, light pollution is one of the main factors causing the reduced population of fireflies.

These artificial lights reduce the dark open space they desperately need to find a match as we know that males have unique and specific flash patterns to attract females’ attention. If this process is interrupted by another light, mating will not occur.

As a result, the females won’t produce eggs, and their numbers are reduced in the wild. Therefore, reducing the light exposure in your garden is crucial, so lightning bugs do not hesitate to visit and stay.

You can turn off the lights in the part of the garden that is overgrown with beneficial plants for the insects. That way, they can more easily show off their bio-luminescence lights.

6. Collect Wood Piles

Tall grass is a favorite place for fireflies to live and breed, but the wood piles provide a great alternative to inviting them to your gardens. How so? Because the woods resemble weathered wood on the forest floors, which are their natural habitat.

Given the females love to stay on the ground, they especially favor this pile. In addition, the female lightning bugs also use rotten wood to lay their eggs. Moreover, the wood piles will also increase the humidity that these flying insects like.

7. Use Artificial Flashing Lights

Where there are females, that is where the male fireflies approach. You can use this fact to attract more lightning bugs to visit your garden. Contrary to the females who stay on the ground, male fireflies prefer to fly around to find a mate.

At this point, the females will display a unique light from their lower abdomen that will be captured as a code by the males. They will also show a flash pattern in return. If they match, they will soon die.

With this scheme, you can make light imitations of female fireflies using a Tumblr LED light and a timer. Make sure you choose a tiny lamp to resemble their natural light with a greenish-yellow color.

Do not use the blue lamp, as lightning bugs cannot recognize such a color.

Next, install these lamps on your porch or garden to attract them at night. But we recommend observing the light pattern before determining the duration of the flashing time to suit the behavior of the females that live around your park.

How Do You Increase the Firefly Population? (Step by Step)

The most appropriate way to increase the population of fireflies is to provide environmental conditions that mimic their natural habitat while providing their favorite foods.

Apart from planting native plants, tall grasses, or ornamentals, adding water features, and adjusting the humidity and temperatures, you can also do this by using compost. Whoops! How come? Read the following step-by-step on how to do it!

Let the litter leaves on the ground. Don’t rake them! Besides the tall grass, female fireflies usually lay their eggs on the damp leaves of the forest floors.
Collect the leaves from the bags. You will need around 5-15 bags to make compost.
Provide moist conditions for the bags by wetting them on the shady lawn areas. You must maintain such a condition (or wet) for about 3-6 months or a year at max. Humidity is critical as it is generally favorable for the larvae and the fireflies.
After that, you can observe some snails, slugs, and worms living in the compost. They are the favorite meals for the lightning bug larvae.
Next, take out the compost and till it in your garden soil around the mounds. Do this step by step for 5-15 years and wait till the fireflies happily live in your garden.

How Do You Make Lightning Bugs Stay in Your Garden? (Step by Step)

While there are many ways to invite fireflies to your garden, they will leave quickly if living conditions are disturbed. So, we would love to include step-by-step steps to keep them in your garden longer!

Take good care of the fireflies’ natural habitat, such as adjusting the humidity and temperatures, planting native plants to keep moisture, and avoiding light pollution.
Make sure your garden provides adequate food sources for them. It will include snails, worms, slugs, pollen, and nectars.
To maintain their food intake, you may want to try composting as it will attract the soft-bodied insects (check out the previous section for more info).
Don’t apply any chemical pesticides, as they will turn away the fireflies.
Don’t rake the litter leaves as there may be a lot of fireflies eggs there. These eggs can signify that your fireflies are comfortable hanging around your yard.

Can You Buy Fireflies?

These light-emitting insects suffer from the devastating loss of their natural habitat due to massive building construction, light pollution, and excessive use of pesticides and insecticides.

As a result, the population of fireflies continues to decline and even requires conservation efforts to prevent extinction in the wild. And for that reason, you cannot buy fireflies.

In addition, they are very susceptible insects to be moved from one habitat to another, in this case, online purchasing. For example, if you move them from one state to another, there is a high risk of them dying during transport since they are very fragile. This can cause us to lose even more numbers of this flying insect.

Moreover, fireflies are also collected for research purposes, especially in biomedical and food safety research. Why? Because they produce luciferase or luciferin, enzymes and chemical compounds generate light.

Of course, this practice is extremely harmful to the bug population as they will die from the extraction of the chemicals. According to the firefly project, this practice is, sadly, still ongoing in Tennessee.

The more people who hunt them in their natural habitat just to get money, the more damaged the moist forests that are home to fireflies are. Imagine your future generation cannot witness the beauty of these light-emitting insects. How sad!
