11. Not All Insects Have Wings
While most insects are famous for their wings—usually two pairs—not all insects can fly.
Certain groups, such as fleas, lice, and many ants, are completely wingless.
This adaptation suits their specialized lifestyles, whether it’s parasitizing hosts or living in underground colonies.
Winglessness demonstrates the remarkable ways insects have evolved to thrive in unique ecological niches, proving flight isn’t always necessary for survival or success.
