Discovering silverfish
Facts and information about Silverfish
Silverfish belong to the order Zygentoma and are scientifically known as Lepisma saccharina. These small insects are commonly found in homes, especially kitchens, bathrooms, basements and bookshelves, and are nocturnal, drawn to dark spaces.
They do not cause harmful diseases in humans, though some people may get allergy symptoms or coughing on contact. They can damage books and papers, and are drawn to starchy foods, which is why kitchens are a frequent hotspot.
They are named for the silvery-grey scales covering their bodies.
Biology
Life Cycle of Silverfish
Eggs are laid in hidden crevices; nymphs resemble miniature adults and molt before reaching a metallic adult stage.
Nymph Stage
Nymphs resemble miniature adults and undergo multiple molts as they grow, feeding on starches, paper and organic materials.
Adult Stage
After completing these molts they reach adulthood, when their bodies develop a dark, metallic shine.
