The botfly, also known as Cuterebra is a type of insect that lives parasitically. They are known to lay eggs in the skin of mammals including humans. Their larvae then feed on the tissues of the host before eventually emerging from the host’s body to continue their development into adult bots. Botflies are known to be found in some regions of the world, including Central and South America, Africa, and parts of Asia. In this article, we are going to explore the origins of this peculiar insect, and try to understand where botflies come from.
What are botflies?
The botfly is a type of insect that belongs to the family Cuterebridae. They are endemic to some parts of the world, including Central and South America, Africa, and Asia. Botflies are known to resemble bees in appearance, with a stout body, large eyes, and hairy legs. These insects are capable of laying eggs on the fur or skin of mammals, including humans.
Where do botflies come from?
The botfly is native to Central and South America, where it lives in the wild. However, the insect has been known to spread to other parts of the world, including Africa, parts of Asia, and some regions of the United States. The distribution of botflies is largely affected by the presence of suitable hosts for their larvae. They are known to lay eggs on the skin or fur of animals, including humans, and their larvae then develop under the host’s skin for up to eight weeks.
Life cycle of botfly
The life cycle of botflies is characterized by four developmental stages – egg, larva, pupa, and adult. Female botflies lay eggs on the skin of the host, which eventually hatch into larvae. These larvae then burrow into the host’s skin, where they feed on the host’s tissues. Once fully developed, the botfly larvae emerge from the host’s body in order to pupate and become adult botflies.
Types of botflies
There are several species of botfly, each with a different distribution and host preference. Here are some of the most common types of botflies:
1. Dermatobia hominis
The Dermatobia hominis, also known as the human botfly is one of the most common types of botflies. These insects are known to lay their eggs on the skin of humans, where they develop into larvae and feed on the host’s tissues. Human botflies are known to be found in Central and South America, as well as some parts of Mexico.
2. Cuterebra fontinella
The Cuterebra fontinella, also known as the common rabbit botfly is a type of botfly that is found in North America. These insects are known to lay their eggs on the skin or fur of rabbits, where the larvae then develop and feed on the host’s tissues.
3. Cuterebra emasculator
The Cuterebra emasculator is a type of botfly that is found in North America. These insects are known to lay their eggs on the skin or fur of squirrels, where the larvae then develop and feed on the host’s tissues.
How botflies are transmitted to humans
Botflies are known to lay their eggs on the skin of mammals, including humans. These eggs can be transmitted to humans through contact with infected animals or through the bite of infected mosquitoes. Once the eggs hatch, the larvae then burrow into the skin of the host, where they feed on the host’s tissues.
How to remove botfly larvae from the skin
Removing botfly larvae from the skin can be a tricky process, and should only be done by a medical professional. Here are some of the most common methods used to remove botfly larvae from the skin:
- Surgery
- Application of petroleum jelly
- Application of adhesive tape
- Suffocation with vaseline and adhesive tape
Preventing botfly infection
Here are some of the best ways to prevent botfly infection:
- Wearing protective clothing when in areas known to be inhabited by botflies
- Using insect repellents that contain DEET
- Avoiding sleeping on the ground outdoors
- Regularly washing and inspecting your skin for signs of botfly infestation
Conclusion
Botflies are fascinating insects that are native to some regions of the world, but can also be found in other parts of the world. They are known to lay their eggs on the skin or fur of mammals, including humans, where the larvae then develop and feed on the host’s tissues. While botfly infestation can be uncomfortable and potentially dangerous, it is preventable with the necessary precautions.

FAQs
Q. How long do botflies live?
A. Adult botflies typically live for just a few days, during which time they mate and lay eggs on the skin or fur of the host.
Q. Where are botflies found?
A. Botflies are primarily found in Central and South America, as well as some parts of Africa and Asia. However, they have been known to spread to other parts of the world as well.
Q. Can botflies infect humans?
A. Yes, botflies can lay their eggs on the skin of humans, where the larvae then develop and feed on the host’s tissues.
Q. What are the symptoms of botfly infection?
A. Symptoms of botfly infestation include itching, redness, and the presence of a raised bump on the skin that may be filled with pus.
Q. How can botfly infestation be prevented?
A. Botfly infestation can be prevented by wearing protective clothing when in areas known to be inhabited by botflies, using insect repellents that contain DEET, avoiding sleeping on the ground outdoors, and regularly washing and inspecting your skin for signs of botfly infestation.
