Love Bug: All You Need to Know About This Adorable Insect

The Love Bug, also known as the “kissing bug,” is a small insect notorious for its habit of biting humans near their lips or eyes, often while they sleep. These bugs can transmit the parasite Trypanosoma cruzi, which causes Chagas disease, a potentially life-threatening illness. Found mainly in the southern United States, Central America, and South America, the kissing bug has garnered increasing attention due to its potential health risks.

To identify a Love Bug, look for its distinct oval-shaped body, ranging from ½ to 1 inch in length, and a long, cone-shaped head. While their appearance may vary depending on the species, these nocturnal insects often have black or brown bodies, with lighter colored wings and stripes across their abdomen. Recognizing and understanding the Love Bug and its habits can help protect you and your loved ones from potential health issues.

It’s important to take precautions and be aware of the environments where Love Bugs are commonly found, such as woodpiles, rodent nests, and areas with large populations of dogs. Ensuring that window screens and doors are well-sealed can help keep these insects out of your home, and following proper pet care guidelines can minimize the chances of contracting Chagas disease.

Love Bug Basics

Origin and Distribution

Lovebugs (Plecia nearctica) are a species of insects native to Central America. They have spread throughout the southeastern United States, including Florida.

  • First observed in the U.S. during the 20th century
  • Climate and habitat contribute to their distribution

Thorax Red/Orange Red/Orange

Life Cycle

Lovebugs have a short life cycle, divided into four stages – eggs, larvae, pupae, and adults.

  1. Eggs: Females lay eggs in decaying vegetation.
  2. Larvae: Larval stage lasts for 2-3 weeks, feeding on decaying plant material.
  3. Pupae: After about 2 weeks, the larvae form protective cocoons and pupate for 7-10 days.
  4. Adults: Lovebugs emerge as adults, living for approximately 3-4 weeks, feeding on nectar.
  • Adults are often seen flying in pairs, with the male and female attached.
  • Mating season occurs twice a year, spring and late summer.

Love Bug Behavior

Mating Season and Swarms

Love bugs (Plecia nearctica) are small flying insects known for their unique mating behavior. They typically have two mating seasons per year, one in May and another in September. During these periods, love bugs form large swarms, which can become a nuisance for people in affected areas. Here are some key features of love bug mating behavior:

  • Mating during flight
  • Couples remaining attached, sometimes forming a “double-headed” appearance
  • Often referred to as “honeymoon flies” or “march flies”

Love bugs are known for their unique way of mating while in flight. This peculiarity has earned them several nicknames such as “honeymoon flies” and “march flies.” Mating love bugs can sometimes be seen as a single insect due to the male and female being attached at the head and abdomen during mating, forming a “double-headed” appearance. During the love bug season, these mating swarms can become quite a nuisance.

Environmental Impact

Although love bug swarms may be annoying, their environmental impact is limited. These insects typically prefer warmer temperatures for mating, so their presence is more common in southern regions. The key factors affecting their environmental impact include:

  • Temperature preferences: love bugs thrive in warmer temperatures
  • Limited geographical range: mostly found in southern regions

While love bugs can create temporary annoyance during their mating seasons, their overall impact on the environment is not severe, and their swarms usually dissipate as temperatures change or as the season progresses.

Car Issues and Remedies

Damage to Paint and Windshields

Love Bugs are notorious for causing damage to car paint and windshields. Their acidic remains can etch paint and glass if not removed promptly. Here are common problems and solutions:

  • Paint Damage: Bug splatters can cause the paint to chip or fade.
    • Remedy: Wash the car with soap and water as soon as possible, and consider applying a coat of wax for protection.
  • Windshield Damage: Bug residues can impair visibility and cause streaks on the glass.
    • Remedy: Clean the windshield with a water and soap solution, and use a windshield treatment for added protection.

Cleaning and Protection Tips

Keeping your car clean and protected from Love Bug damage is essential. Here are tips and examples of products to help:

Over the years, our website, has received hundreds of letters and some interesting images asking us about these insects. Scroll down to have a look at some of them.

Letter 1 – Dead Lovebug


Help with a bug
I found this bug, dead, in my son’s room. I have no idea what it is, but he has recently suffered from some bites. I was wondering 1) what this might be, and 2) could it be the culprit of the bites?
Thank you!

Is your son’s room in Florida? We believe this is a male Lovebug in the genus Plecia, a Fly.

No, not Florida. Sorry for not including that in my original e-mail; we ARE in Georgia, though, and I’ve heard of Lovebugs in this area. Just never seen one before. If this isn’t what could have bitten him, I will have to keep looking. Thanks!

Letter 2 – Lovebugs


Love Bug Threesome
I see hundreds of Florida Love Bugs every day this time of year (mainly on my windshield) but I have never seen them having a threesome. Do they compete for mates when they are already attached?

Hi Mark,
There is always competition for mates in the animal kingdom. We imagine the spurned suitor is hoping for some opportunity.

Letter 3 – Lovebugs Mating


New Orleans Love Bug
My name is Yvonne Nieves. I live in a suburb of New Orleans called Avondale. This area that I live in is a pretty swampy area as most of Louisiana is. My question to you is that the photos that I am sending to you are photos of what we call here Love Bugs. No one here knows where they come from, what is their purpose, why do they come twice a year, the Spring and in the Fall. We are pretty much getting over them right now. They usually last for 2 weeks, then they are completely gone and there will be no signs of them anylonger. They are present in the millions and they are probably the most aggravating insect that lives around here for just those 2 weeks every Spring and every Fall. The bugs are connected by their tails, most of them in pairs, and very few that are alone. One has a head or is it eyes bigger than the other as you can see in the photos. If you have any idea of what these bugs are, and their correct name, and why and where they come from, I would greatly appreciat the information, and so would thousands of other people. Sincerely,
Yvonne Nieves

Hi Yvonne,
These really are Lovebugs, the common name for several species of March Flies in the genus Plecia. Female Lovebugs have the small eyes and males have the large eyes. Why they exist is a philosophical question we would prefer not to tackle.
