asilidae
Definition
Noun: 1. A family of predatory flies: Asilidae is the scientific name for a family of insects commonly known as robber flies. They are characterized by their stout, often hairy bodies, a distinct "beard" (mystax) on the face, and a long, strong proboscis used to inject prey with neurotoxic saliva.
Usage Notes

- It is always treated as a singular noun when referring to the family as a taxonomic group (e.g., "The Asilidae is a diverse family."). However, when referring to multiple individual flies of this family, the plural "asilids" is often used.
- The word is typically capitalized because it is a proper noun denoting a specific biological family.
Examples
- The predatory habits of Asilidae make them important for controlling pest insect populations.

- Many species within the Asilidae family exhibit remarkable mimicry of bees or wasps.
