Aptery
![Female velvet ants, are an example of secondary aptery as they belong to a taxon of winged insects -the superfamily Vespoidea.- Furthermore, males of velvet ants are fully winged](/Images/godic/202412/21/Velvet_ant_91181548.JPG")
Aptery is the anatomical condition of an animal completely lacking any kind of wings. An animal with this condition is said to be apterous.
Most animal species belong to and are phylogenetic descendants of apterous taxa. These groups are said to be primarily apterous.
