Where did love bugs in florida come from


Love bugs, also known as the Florida double-decker fly, are a common sight in Florida during summer and spring. However, many people do not know where these unlikely insects came from. This article takes an in-depth look at the history of love bugs in the Sunshine State and how they ended up becoming such a staple of life there.

The first sighting of love bugs in Florida was reported by a newspaper on Panacea, located near Tallahassee, on April 15th 1940. Reports began increasing along the Gulf coast until around 1956/1957 when they spread throughout most of the state. It is believed that they originated in Central America and hitched a ride on unmarked cargo trucks heading to Cuba and then onward to Southern U.S states – including Florida – most likely due to their strong affinity towards warm temperatures.

One theory suggests that when Panama Canal opened in 1914, this created an excellent pathway for travel between South America and North America, allowing lovebugs to quickly cross between two continents – although this has yet to be confirmed. Another popular theory is that tropical hurricanes carried lovebugs far away from their native habitat before depositing them across Southern states like Texas and Louisiana; indeed even though lovebugs prefer coastal areas and wetlands these days because of its moderate temperature levels, accounts suggest that these may very well be where their original homes were before people began importing larger amounts of goods to warmer climates.

History of Lovebugs in Florida

Lovebugs are a type of fly native to Central America, but they can now be found in the south-eastern United States. The first recorded sightings of lovebugs in Florida date back to 1940s, making them a relatively recent addition to the state’s ecosystem. But how did lovebugs make their way to Florida in the first place, and what has their story been? Let’s explore the history of lovebugs in Florida.

Origin of Lovebugs

Lovebugs, scientifically known as Plecia nearctica are a species of true fly from the family Bibionidae. They are perhaps most noted for the short period of time each year in which they cohabitate in massive swarms – they typically mate while flying and may appear as a cloud around trees or fields. While the vast majority of lovebug sightings occur in Florida, these buzzing bugs can be found across most of Texas, North Mexico and parts of the Caribbean.

The origin story of lovebugs is unique. In 1947, University of Florida entomology student Dr. Harold Denmark worked with Florida’s Experiment Station alongside Dr. Hooper Atwood to introduce European strains of piss fly into the wilds of southeastern US states including Florida as part mosquito control research and testing for possible biological control efforts against malaria-transmitting mosquitoes. Those attempts failed but what emerged was a population explosion of Love Bugs that persists to this day from east Texas all the way down to Panama City Beach, FL and eastward through Tampa Bay area shoreline locations like New Port Richey & Apollo Beach all along submerged beach fronts (where ocean current meets sand dunes) leading to those spots being most popularly associated with LoveBug sightings today – especially late August/Early September for their two week seasonal mating season frenzy!

Spread of Lovebugs

Lovebugs (Plecia nearctica) are small black insects that are common around Florida and the Gulf Coast area. They are also known as “honeymoon flies” and “double-headed bugs” due to their inseparable pairings. These bright red bugs have baffled the public for years with their sudden appearance and disappearance every year.

With the mystery solved, lovebugs’ presence in Florida can be explained by its long history of spread along the Eastern and Central United States. During World War II, a species of lovebug native to Central America found its way into a shipment of citrus fruits delivered to Mobile, Alabama. The insect quickly spread by air currents across the South, reaching as far north as Ohio and Maryland over time, before finally finding its way to Florida in 1952 through carriers such as animal feed shipments or trucks carrying items from elsewhere in US.

Since then, lovebugs have become a common sight in Florida during late April through early June each year when they emerge in large numbers after hatching from larvae during warmer temperatures. They can migrate great distances with help from winds which often deposit them onto roads, buildings, cars and other objects along their journey. Many theories have circulated regarding how they got their name but it is likely derived from their heart-shaped form when seen together or less frequently seen when gathering around flowers or on trees.

Life Cycle of Lovebugs

Lovebugs are a type of fly found in the Gulf Coast region of the United States. They are most commonly seen in Florida, but they can also be found in other southern states. Lovebugs are, in fact, not bugs but flies. They are scientifically known as Plecia nearctica and can go through many stages of development in their short lifespan.

Let’s delve into the life cycle of lovebugs to learn more about them.

Egg Laying

Once copulation has occurred and mating is complete, female lovebugs will lay approximately 50-100 eggs at a time. The egg laying usually takes place over the course of 1-3 days and is most frequently done on areas of short grass, gravel driveways and even cars. Eggs are often found in clusters of 20-30 on the exposed soil surface. During this life cycle stage, lovebugs can lay 2-4 batches of eggs throughout their lifespan of 30 days.

Once these eggs have been dispersed on these surfaces, they are often difficult to spot due to their small size and nearly translucent coloration. At hatching each egg shell can be seen cracked open but the emerging larvae remain within this shell for several hours until they gain enough strength to disperse into their environment. The incubation period for lovebug eggs can take up to three weeks depending on temperature and weather conditions. In warmer climates, such as Florida, the hatching period may be reduced by half in comparison to more temperate regions such as Michigan or Oregon.

Larval Stage

The larval stage of the lovebug’s life cycle is one of the first noticeable signs of their presence. At this point, they look like small maggots or fly larvae and are found in moist, dark areas. They feed on decaying organic matter, such as plant debris and manure.

During this stage, they can be found under leaves or wood piles, or even in cow pastures, as love bugs excel at finding food sources that won’t be disturbed easily by things like strong winds or heavy rains.

Once the larvae reach maturity, after about three to six weeks depending on temperature and other environmental conditions, they migrate away from their food source to start pupation. Pupation takes another three weeks as new adult lovebugs form inside their cocoons. When the adult bugs emerge from the cocoons, they start a new cycle of searching for a mate and reproducing before eventually dying off again the following springtime.

Pupal Stage

The pupal stage of the lovebug’s life cycle is a time when they remain completely quiescent within their protective cocoon. Around this stage, the lovebugs begin to develop wings and their exoskeleton hardens in preparation for adult life. The pupal stage of a lovebug’s life cycle lasts approximately one to two weeks, after which they emerge as adults and can make their maiden flight.

Once the lovebugs reach adulthood, they mate quickly and then enter the final stage of development: death. In less than four weeks, they complete their reproductive lifecycle by dying off each summer season shortly after mating. The population numbers vary from one year to the next depending on environmental factors such as rainfall and climate changes. As long as environmental conditions are favorable for reproduction, populations will remain stable and new generations of lovebugs will be born into Florida’s ecosystems each year.

Adult Stage

The adult stage of the lovebug life cycle lasts for about two months. Adult love bugs typically survive in dense areas with plenty of foliage, such as oak trees, fields and parks. During this time, they are most active during the day and are particularly attracted to light-colored surfaces, such as vehicles and streetlights. They consume nectar from flowers or sometimes other sugary substances, while they also seek out potential mates by releasing pheromones into the air.

Male and female lovebugs often join in groups known as swarms. Swarms usually occur near midday when temperatures reach their highest point in the day – this helps them conserve energy and ensure successful mating. During a swarm, hundreds of wings appear out of nowhere moments before clouds of smokey black insects fill the sky. Lovebugs pair off with their designated mate before embarking on their journey to new habitats together until daybreak when they split up again in search for a meal or suitable nesting environment.

When paired males and females can be seen flying around in synchronized patterns resembling figures from ballroom dancing often referred to as the “Lovebug Dance” by enthusiasts.

Impact of Lovebugs on Floridans

Lovebugs, also known as March Flies, are a species of fly native to Central and South America. In the late 1940s and early 1950s, this species was accidentally introduced to Florida through the release of contaminated shipments from the tropics. Since then, lovebugs have become a major nuisance for Floridans, turning their sunny days into a flurry of buzzing wings.

Let’s take a look at the impact of lovebugs on Floridans:

Damage to Cars and Houses

Lovebugs are native to Central and South America, but they have been making periodic appearances in Florida since the late 1940s. Like most insects, they love hot and humid climates – can you blame them? They are also generally more active during wetter months.

Lovebugs are relatively harmless; however, their sheer abundance can be a nuisance for Floridians. Cars in particular bear the brunt of this population explosion – their sap-like droppings can coat cars in sticky residue that is difficult to remove. And if cars aren’t hosed off quickly after being exposed, the residue could end up ruining a car’s paint job as it bakes in the summer heat.

Houses and other structures may also receive damage from lovebugs if left untreated or exposed for long enough periods of time. Their droppings can lead to discoloration on vinyl siding, brick facades and certain types of wood surfaces – all while attracting pesky mold that needs to be dealt with promptly.

Impact on the Environment

Love bugs are known to cause some minor damage to structures wherever they gather in large numbers. The bodies of the adult bugs contain an acidic substance, and when masses of these bugs land on vehicle windshields, grills and air intake ducts, the fluid can corrode unprotected metal and plastic parts. This poses a particular problem in Florida’s coastal communities, since salt water spray carries further inland and can speed up corrosion in vehicles due to love bug acid accumulation.

However, lovebugs have had a mediocre impact on the environment of Florida overall. In contrast to common belief, they do not pose major threats as pests or vectors of disease or plant destruction, even though they do affect urban growth somewhat with their tendency to congregate near areas with bright lights and moist climates near motorways. Their emergence has largely been an interesting footnote in ecology history rather than having a significant long-term effect on nature balance—although homeowners without air conditioning may have their own opinion on that matter!


In conclusion, the origin of Lovebugs in Florida remains a mystery. While Louisiana, Texas, and Florida are the only states in the U.S where Lovebugs seem to be concentrated, they have been known to appear in other areas when conditions are right. It is believed that the bugs had been living in Central and South America before making their way to North America. They are believed to have gotten attached to Mexican cars crossing over into Texas and then making their way on other vehicles throughout the south.

One thing experts can agree on is that once they got here, they’re not going anywhere and continue to be a nuisance for state residents every Spring and Fall season.
