botfly

Thân thiện

A botfly lands on the arm of a hiker in a tropical forest.

Definition

Noun: 1. A stout-bodied, hairy fly: A type of true fly (order Diptera) characterized by a robust, hairy body. The adult fly itself does not feed on or directly harm mammals. 2. A parasite via its larvae: The defining characteristic of a botfly is that its larval stage (maggot) is an obligate parasite that develops under the skin or in the body cavities of mammals, including humans, livestock, and rodents. The adult fly's primary purpose is reproduction to continue this parasitic lifecycle.

Examples

• The veterinarian treated the horse for an infestation caused by the botfly.
• One species of botfly lays its eggs on mosquitoes, which then transfer the eggs to human hosts.
• The botfly is more dangerous in its larval stage than as an adult insect.

Advanced Usage

• The term "bot" is often used specifically to refer to the parasitic larval stage itself (e.g., "The vet removed a bot from the horse's stomach.").
• In entomology, botflies are classified into several families, most notably Oestridae. Discussions may refer to "oestrid flies" as a scientific synonym for botflies.

Variants and Related Words

• Bot (noun): The parasitic larva of a botfly.
• Warble fly (noun): A specific type of botfly (genus ) that causes warbles, or subcutaneous swellings, in cattle and other animals.

Synonyms

• Parasitic fly: A general descriptive term.
• Oestrid fly: A formal, taxonomic synonym.

Notes on Meaning

The core meaning of "botfly" always combines the two aspects: the physical adult fly and its parasitic larval behavior. It is not used to describe just any stout, hairy fly. The word inherently implies a parasitic relationship with mammals.
