NAME OF INSECT: Silverfish
HABITAT AND RANGE: Silverfish normally live outdoors under rocks, bark and leaf mold, in
the nests of birds and mammals, and in ant and termite nests. However, many are found in
houses and are considered a pest, or at least a nuisance, by homeowners. Usually they are
found trapped in a bathtub, sink, or washbasin.
DIET: The Silverfish will feed on almost anything. A partial list includes dried beef,
flour, starch, paper, gum, glue, cotton, linen, rayon, silk, sugar, molds, breakfast
cereals, book bindings, and wall paper paste
MOUTH PART TYPE: The Silverfish has a concealed chewing mouth part.
LIFE SPAN: Most Silverfish bugs live for about two to 2 1/2 years.
COMPLETE SCIENTIFIC CLASSIFICATION: Kingdom: Animalia Phylum: Arthropoda Sub-phylum:
Chelicerata Class: Insecta Order: Thysanum Family: Lepismati Genus: Metalus
Species: Gerrainus
LIFE CYCLE: Silverfish undergo incomplete metamorphosis. Adults lay eggs in small groups
containing a few to 50 eggs. The eggs are very small and deposited in cracks and
crevices. A female normally lays less than 100 eggs during her life span . Under ideal
conditions, the eggs hatch in two weeks, but may take up to two months to hatch.
The young nymphs are very much like the adults except for size. Several years are
required before they are sexually mature, and they must mate after each molt if viable
eggs are to be produced. Populations do not build up rapidly because of their slow
development rate and the small number of eggs laid.
ECONOMIC IMPORTANCE: Silverfish sometimes feed on book binding and the paste that holds
on wall paper causing damage to many houses.
IS IT A SOCIAL INSECT? Yes I think that the Silverfish is social because it lives in
colonies.
