Summary

Cuterebrinae, the New World Skin Bot Flies, are a subfamily of large, robust, parasitic flies known for their life cycle involving mammalian hosts, including rodents and occasionally primates and humans.

Physical Characteristics

Up to 30 mm in size; robust body.

Identification Tips

Look for large, hairy flies with a characteristic parasitic lifestyle.

Habitat

Primarily in regions where hosts like mammals (rodents, rabbits, primates) are found.

Distribution

Precinctive to the New World; includes various habitats across North America and South America.

Diet

Parasitic as larvae; feed on the tissues of their mammalian hosts.

Life Cycle

Life cycle includes egg-laying on the host, followed by larval development within the host's skin.

Reproduction

Females deposit eggs on or near host animals; larvae enter the host and develop.

Predators

Various birds and other carnivorous insects may prey on adult flies.

Ecosystem Role

As parasites, they can influence host population dynamics and ecosystem health.

Economic Impact

Potential to impact livestock health, particularly with species like Dermatobia hominis.

Cultural Significance

Dermatobia hominis, also known as the Human Bot Fly, has notable relevance in human-inhabited areas due to its ability to infest humans.

Health Concerns

Dermatobia hominis can cause cuterebriasis in humans, leading to painful lesions.

Collecting Methods

  • Malaise traps
  • Hand collection at host sites

Preservation Methods
