Velvet ants are fascinating insects that are actually wasps, not true ants. They are famous for their bright colors, dense hair-like bodies, and extremely painful sting. These insects are mostly solitary and are commonly found in dry, sandy, and open habitats where they search for underground nests of other insects.
Despite their small size, velvet ants play an important ecological role as parasitoids, helping control populations of ground-nesting bees and wasps. In this guide, you’ll explore 25 different types of velvet ants, along with their identification features, habitats, and behaviors.
