Project Description


Lepisma saccharina(L.)

Size & Appearance:
What we commonly call a “silverfish” is a small, wingless insect and gets it’s name from the silvery light grey and blue color, combined with the fish-like appearance of its movements.

Silverfish two small compound eyes and are nocturnal insects. They are typically 13–30 mm (0.5–1 in) long, with abdomens that taper at the end, giving them a fish-like appearance. The newly hatched are more white in appearance, but develop a grey hue and metallic shine as they get older. Silverfish have three long Circe at the tips of their abdomens, one off the end of their body, one facing left, and one facing right.

[jbox title=”Interesting Fact”] Silverfish consume matter that contains polysaccharides, such as starches and dextrin in adhesives. These include book bindings, carpet, clothing, coffee, dandruff, glue, hair, some paints, paper, photos, plaster, and sugar.[/jbox]

Silverfish have long antennae, and move in a wiggling motion that resembles the movement of a fish. This, coupled with their appearance and silvery scales, influences their common name. Silverfish typically live for two to eight years. Silverfish are agile runners and can outrun most of their predators (including wandering spiders and centipedes). However such running is only possible on horizontal surfaces, as they lack any additional appendages and, therefore, are not fast enough to climb walls at the same speed.

Silverfish are a cosmopolitan species, found in Africa, the Americas, Australia, Eurasia, and other parts of the Pacific. They inhabit moist areas, requiring a relative humidity between 75% and 95%. In urban areas, they can be found in attics, basements, bathtubs, sinks, kitchens and showers.
