Lepisma saccharina is a silverfish insect. It is a member of the order
Thysanura. This particular species is found in most parts of the world. Lepisma
saccharina is silvery blue. Juvenils are white. The favorite components of the
diet of this insect include materials which have polysaccharides or starch. They
include glue, sugar, and paper. Silverfish also eat cotton and silk fibers.
Sometimes they prey on other insects and even consume their own molted skin.
Silverfish are sometimes referred to as bristletails.
The body is up to 3/4 in. (19 mm.) long. It is elongate-oval shaped and
flattened. There are two long antennae. Three tail-like projections are at the
end of the abdomen.
A female can lay more than 100 eggs during her lifespan. She lays them in
small groups or singly in crevices and cracks. The process of going from egg to
nymph to adult generally takes 4-6 weeks. Nymphs are about 1/20 in. (1.27 mm.)
in length. The lifetime of a silverfish is 2-3 years. Molting occurs
continuously during its lifetime. Silverfish are especially active at night.
House centipedes, earwigs, and occasionally spiders eat silverfish.
The male lays a spermatophore and the female then takes it into her body by
means of her ovipositor. She fertilizes her eggs and lays them later.
Jeffrey K. Barnes wrote an article titled Silverfish. It was published by
the University of Arkansas Arthropod Musuem on October 6, 2005. Barnes states an
important point about Lepisma saccharina in this excerpt:

It prefers cool, damp situations, developing and reproducing best at 72-81
degreees F and 75-97% relative humidity.

This excerpt says:

They are cannibalistic, feeding on cast skins and injured individuals of their
own species.
