Female botflies capture small flying insects, such as mosquitoes or other biting flies, and attach their eggs to the insects' bodies. When the insect comes into contact with a mammal, the eggs hatch, and the botfly larvae attach to the host's skin.
Infestation (Myiasis): Once attached to the host, botfly larvae burrow into the skin, where they continue their development. The presence of the larvae under the skin causes a condition known as myiasis, characterized by painful swellings or boils. The larvae feed on the host's tissue and grow within the subcutaneous tissues.
Pupation: After several weeks of feeding and growing inside the host's body, the mature botfly larvae emerge from the skin to pupate in the soil. The pupation stage is when the larvae transform into adult flies.
Hosts: Botflies have a wide range of mammal hosts, including rodents, rabbits, squirrels, and domestic animals like cats, dogs, and livestock. Some species of botflies, such as the human botfly (Dermatobia hominis), can also parasitize humans.
Human Interaction: Human infestations with botfly larvae can occur in regions where the flies are present. Infestations usually happen when a female botfly captures a mosquito or other insect carrying its eggs, and the insect then bites a human, depositing the eggs on the skin. The larvae subsequently hatch and burrow into the skin, causing painful and itchy boils.
Prevention and Treatment: Preventing botfly infestations involves avoiding exposure to botfly-carrying insects. Once infested, treatment involves careful removal of the larvae from the skin by a medical professional, followed by proper wound care.
Botflies are a fascinating group of flies with a unique and complex life cycle that involves parasitizing mammals to complete their development.
