Gnat
A gnat is a common name for several kinds of very small flying insects, especially small flies.
A gnat is a common name for several kinds of very small flying insects, especially small flies. In everyday use, the term is broad and not a single scientific classification; it may refer to biting or non-biting insects in different fly groups. Gnats are often nuisance insects and are commonly associated with swarms, moisture, plants, or decaying organic matter.
Taxonomy and usage
Gnat is a loose common name, not a formal scientific taxon. Different regions use it for different small flies, including biting and non-biting types.
Physical characteristics
Gnats are typically very small insects with slender bodies, long antennae, long legs, and one pair of wings. Their appearance often leads to confusion with mosquitoes and other small flies.
Habitat and behavior
Gnats are commonly associated with damp environments, houseplants, soil, fungi, and decaying organic matter. Some species form swarms, often at dusk, especially during mating.
Types commonly called gnats
The name may refer to fungus gnats, biting midges, black flies, fruit flies, or other small flies depending on local usage. In some contexts, the insects are non-biting nuisance species, while in others they bite humans or animals.
Key facts
- The word gnat is a broad common name for many tiny flies rather than one species or family.
- Gnats belong to the insect order Diptera, the true flies.
- Many gnats are small, long-legged, and weak fliers.
- Some gnat-like insects are biting, while others are non-biting.
- Gnats are often noticed near moisture, plants, soil, fungi, or decaying organic material.
In Canada, 'gnat' is used as a broad common name for several small flies, and Canadian readers may encounter them indoors, around plants, or outdoors near damp areas. Orkin Canada notes that there are more than 600 gnat species in North America.[1]
