Silverfish

Lepisma saccharinum

Silverfish are wingless and silvery insects belonging to the order Zygentoma. Although these pest bugs will happily live outdoors in the right conditions, they have also become a nuisance in homes across the Americas, Europe, Asia, Africa, Australia, and Pacific islands.

Their name comes from a combination of their color and their smooth, fluid, movements that resemble those of fish.
