What Is a Botfly? Life Cycle, Symptoms, and Safe Removal Explained
The Botfly is one of the most unusual insects in the world. Known for its parasitic lifestyle, this fly lays eggs on animals and sometimes even humans. Its larvae grow inside a host before turning into adult flies. Although it may sound scary, the botfly plays a role in nature’s balance. Learning about Botfly facts, Botfly habitat, Botfly diet, and the Botfly life cycle helps us understand how complex and fascinating the insect world really is.

Appearance and Physical Characteristics
- Stout and hairy body, often looks like a bumblebee.
- Strong legs and small antennae.
- Usually grey, black, or brown in colour.
- Large compound eyes.
- Adults do not bite or sting.
Habitat and Distribution
The Botfly habitat mainly includes warm tropical and subtropical regions.
- Rainforests and woodlands
- Grasslands with livestock
- Rural and farm areas
- Central and South America (most common)
Different species of botflies target different animals such as cattle, horses, deer, and sometimes humans.
Diet and Feeding Habits
Larval Stage (Parasitic Stage)
- Larvae feed on the tissue of their host.
- They live under the skin of mammals.
- They breathe through a small hole in the skin.
Adult Stage
- Most adult botflies do not feed at all.
- They live only to reproduce.
- Adult life lasts only a few days to weeks.
Behaviour and Lifestyle
This unique strategy helps botflies spread without directly attacking their host.
Botfly Life Cycle
- Egg Stage: Eggs are attached to a carrier insect like a mosquito.
- Larva Stage: Larva enters host’s skin and feeds for several weeks.
- Pupa Stage: Larva drops to the soil and forms a pupa.
- Adult Stage: Adult fly emerges, mates, and repeats the cycle.
What Makes Botfly Special?
Importance and Role in Nature
- Part of the natural food chain.
- Help control animal populations naturally.
- Serve as food for birds and other predators.
- Studied in medical science to understand parasitic infections.
Though unpleasant for hosts, the Botfly importance in ecosystems cannot be ignored.
Amazing Botfly Facts
Interesting Facts About Botfly
- They do not lay eggs directly on humans.
- Botfly larvae create a small breathing hole in the skin.
- They are more common in rainforest areas.
- Proper hygiene and protection reduce infection risk.

FAQs on Botfly: Identification, Life Cycle, and Human Impact
1. What is a botfly?
A botfly is a type of parasitic fly whose larvae grow inside the skin of animals or humans.
- The scientific family name is Oestridae.
- It is also called a human botfly or Dermatobia hominis.
- The adult fly looks similar to a bee.
- The larvae (maggots) live under the skin of mammals.
- They are common in Central and South America.
2. How does a botfly infect humans?
Botflies infect humans by laying eggs that hatch and burrow into the skin.
- The female botfly attaches eggs to mosquitoes or other insects.
- When the mosquito bites a person, body heat makes the eggs hatch.
- The tiny larvae enter through the bite or hair follicles.
- This causes a small swelling called cutaneous myiasis.
3. What is cutaneous myiasis?
Cutaneous myiasis is a skin infection caused by botfly larvae living under the skin.
- It forms a painful or itchy bump.
- The bump may have a small breathing hole.
- You might feel movement inside.
- It is most often caused by the human botfly.
4. Are botflies dangerous?
Botflies are usually not deadly but can cause pain and infection if untreated.
- The larvae damage skin tissue.
- Scratching can lead to bacterial infection.
- Medical removal is often needed.
- Serious problems are rare with proper care.
5. Where do botflies live?
Botflies live mainly in warm tropical regions.
- Common in Central America and South America.
- Found in rainforests and rural areas.
- They prefer areas with livestock and wild animals.
- Rare in cold climates.
6. What animals do botflies infect?
Botflies infect many mammals, including humans and animals.
- Cows and horses (called cattle grubs).
- Dogs and cats.
- Monkeys and wild mammals.
- Humans in tropical regions.
7. How is a botfly larva removed?
A botfly larva is removed by blocking its air supply or by minor medical surgery.
- Doctors may cover the hole with petroleum jelly.
- This forces the larva to come out for air.
- Sometimes a small incision is made.
- Removal should be done by a medical professional.
8. What does a botfly larva look like?
A botfly larva looks like a small, thick, creamy-white maggot.
- It has tiny spines to grip the skin.
- It can grow up to 1 inch long.
- It has a breathing tube at one end.
- It stays under the skin for several weeks.
9. How can you prevent botfly infection?
You can prevent botfly infection by protecting yourself from insect bites.
- Use insect repellent with DEET.
- Wear long sleeves and pants.
- Sleep under mosquito nets.
- Iron clothes in tropical areas to kill hidden eggs.
10. What is the life cycle of a botfly?
The botfly life cycle includes egg, larva, pupa, and adult stages.
- Eggs are attached to mosquitoes.
- Larvae hatch and grow under skin.
- After weeks, larvae drop to the ground.
- They become pupae in soil.
- An adult botfly emerges to restart the cycle.
