Example of a primarily wingless insect in which wing buds never develops

Example of a primarily wingless insect in Protura is wing buds never develop.
Wingless insects are a subclass of small, agile insects, distinguished from other insects by their lack of wings in the present and their evolutionary histories, like silverfish and firebrats.
Some species lacking wings are members of insect orders that generally do have wings. Some do not grow wings at all, having "lost" the possibility in the remote past. Some have reduced wings that are not useful for flying.
