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: MetalusSpecies: 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.
