Find silverfish information at Animal Diversity Web
There are around 370 species from four different families in the order Thysanura. Their distribution is worldwide.
Silverfish live under bark, leaf litter, in caves and other underground dwellings, including mammal burrows. Some species are found in buildings associated with humans. Silverfish can exist under extreme environments. Some tolerate wet, cool regions, and others tolerate the low humidity and high temperatures of arid regions.
Molting occurs throughout the life of the insect. It takes up to two years for a silverfish to complete its development from juvenile to adult.
4 years (high)
Silverfish can live up to four years.
Despite being wingless, silverfish are rapid runners.
Silverfish that are outdoor species are useful decomposers of organic materials.
Collecting: Silverfish may be collected from buildings by placing strips of paper at the edge of a small jar and making a ramp to the floor. Place a bit of dried fruit, raisin, oatmeal or cracker in the jar and check it every day. If silverfish are around, you'll trap them in the jar. Place the trap in an attic, storage room, or cellar for best results. They can also be collected from leaf litter using a Berlese funnel and jar. Outdoors, Silverfish are also found under bark and stones and in fungi. A moist brush will pick them up. Preserve silverfish in 75% ethanol.
