I was among the happy ones, growing up ~ above the East coastline of Virginia where lightning bugs, as we dubbed them, lit our warmth evening summer sky, regularly as early on as May.Today’s term because that these beetles appears to have gravitated towards fireflies. I prefer that too, but I tho fall earlier on mine childhood term of lightning bugs; after all they to be lighting up the night sky like that that a summer storm.

For those the us east of the Rockies through warm and sultry nights, awaiting the come of thefirefliesmeant the arrival of summer.


There are an ext than 2,000 varieties of fireflies, a kind of beetle. Walk you know there room fireflies out West together well, yet they nothing light increase the skies at night? despite their name, no all fireflies glow. Fireflies in the western united States, for example, lack the capability to develop light. Another interesting fact about fireflies is many females nothing fly. Instead, ~ above the East shore at least, they stay in moist leaf litter and also flash come a receptive mate.

Sadly, fireflies are in decline. Thereasons room still to be pinpointedbut experts think habitat loss and light air pollution play a function by interfering v firefly speed patterns. Irradiate from buildings and also streetlights do it daunting for fireflies to signal each other throughout mating season—meaning fewer fireflies. It has actually been detailed flashes of synchronous fireflies get out the synch because that a few minutes after ~ a car’s headlights pass.

Males speed to attract females, and also mating begins when the flash carries the ideal rhythm. The speed of a masculine firefly is only the an initial stage the courtship, and also may not even be the many important. I can’t think I’m around to say this, yet a research shows, dimension matter! Females are more likely to mate with males who provide them a bigger nuptial gift.

Life bicycle of Fireflies

Like allbeetles, fireflies undergo complete metamorphosis with 4 stages in your life cycle: egg, larva, pupa, and also adult.

Egg– In mid-summer, mated females will certainly deposit around 100 spherical eggs, singly or in clusters. Fireflies choose moist soils, and also will lay egg under mulch or sheet litter, whereby the soil is most likely to remain moist. But it different by species. These eggs usually hatch in three- come four-weeks.

Larva– Larvae emerge from their eggs in so late summer, and live in the soil through the winter before pupating in the spring. This is just one of the numerous reasons to save leaf litter in our garden beds. At night the larvae hunt and also eat slugs, snails, and worms. Come consume food, the larvae will certainly capture and inject the victim with digestive enzyme to immobilize it and liquefy that remains.

Pupa– Different species of firefly larva pupate in various ways. As soon as the larva is ready, commonly in so late spring, some varieties construct a dirt chamber in the soil and also settle within it. In other species, the larva attaches itself to a tree’s bark, hanging upside down by the hind end.

During pupation, a remarkable revolution takes place throughout the pupal stage. In a process called histolysis, the larva’s human body is broken down, and also special groups of transformative cells space activated, triggering biochemical processes that transform the insect native a larva right into its adult form. As soon as the metamorphosis is complete, the adult firefly is ready to emerge, usually about 10 work to numerous weeks after ~ pupation.

Adult– when the adult firefly emerges, it has actually one purpose, come reproduce. To uncover a mate, fireflies use a species-specific pattern to situate compatible individuals of the contrary sex.

Typically, the male paris low to the ground, flashing a signal with the light organ on his abdomen, and also a female relaxing on vegetation returns his communiqué. By repeating this exchange, the male hones in on her, and the remainder of the story is happily ever before after.

Adult fireflies nothing live long, averaging around two months; just long enough to mate and lay eggs.

No issue the life cycle, all stages the fireflies glow. Bioluminescence is existing in firefly eggs, larvae, pupae, and adults, and even some larvae living listed below the ground or underwater glow. Part firefly eggs emit a pass out glow if disturbed.

Experts theorize the capacity to emit irradiate helps larvae signal to predators that they aren’t appetizing, since component of the firefly defense system is to develop foul-tasting steroids.

The firefly’s light is the an outcome of the reaction of two chemicals found in your tails, luciferase and also luciferin. Luciferin is warm resistant and provides the glow. Luciferase triggers the flash. Firefly light deserve to be yellow, green, or orange.

Where do Fireflies Live?Fireflies grow in warm, humid climates, i beg your pardon is why they are uncovered on almost every continent top top Earth. Fireflies inhabit forests, fields, and marshes near bodies that water due to the fact that they call for a moist setting to survive. Some species of firefly larvae have gills and are aquatic, while rather live in trees.

What perform Fireflies Eat?As adults, most fireflies feeding on nectar and pollen, yet some nothing seem to eat in ~ all. Those few species that carry their carnivorous lifestyle into adulthood switch from snails to other fireflies. Yikes!

Catching Fireflies

Lightning bugs are so ingrained in our childhood memories. I’m sure everyone top top the East coastline has a storage to share. The peak one is recording them and keeping them in a mason jar for the night.

There is plenty of wait in the seasoned to keep the insects lively for a work or more, and poking holes in the lid will cause the jug to dry out as well quickly. Instead, put a little piece of to wash apple and a little clump of fresh grass in the jar, or moistened record towel in the bottom, maintaining the waiting in the seasoned moist, and it provides the fireflies something come grab onto. The grass is for them to climb on and hide in.

Every day, unscrew the jug lid and also blow throughout the height of the jar. This keeps the air in the seasoned fresh. Don’t placed the jar in straight sunlight.

You don’t need to feed the fireflies. Most adults never ever eat. They did all their eating as larvae. But don’t save them in a jug for much more than 2 or 3 days. Fireflies only live a couple of days or weeks, and we require them external to mate.

Unlike some other insects, fireflies space no bother to us humans. They nothing sting, bite, attack, or bring disease.
