Size
body length about 8 mm
Identification
oblong/elongate yellowish body with dark brown bands and mottled spots on the dorsal surface; stout-bodied (abdomen relatively broad-tipped and often shorter than thorax, giving an overall "chunky" appearance)
Range
cosmopolitan indoors
Habitat
prefers hot places (above 30 degrees C [90 degrees F.]) such as around furnaces and fireplaces, and in the insulation surrounding hot water and heating pipes, but will explore other areas of homes and buildings in search of food
Season
all year indoors
Food
nymphs and adults feed mostly at night on products rich in carbohydrates or protien; stored foods, glues, book bindings, and paper products may be attacked
Life Cycle
eggs are laid in crevices in batches of 50 or so and take 12 to 13 days to hatch; adulthood is reached at about four months of age, and individuals live for several years; simple metamorphosis (egg, nymphs, adult); up to several generations per year
See Also
the former T. campbelli (now T. aegyptiaca) is mostly transparent with a silvery-gray dorsal surface, and is apparently restricted to Ohio
the Common Silverfish (Lepisma saccharina) is slightly larger (10 mm) and more slender, uniformly silver or gray, and is generally not found around furnaces or hot pipes
the Four-lined Silverfish (formerly Ctenolepisma quadriseriata, now synonymized with C. lineata) has 4 lines down its back, and the Gray [or Giant] Siverfish (which includes the former Ctenolepisma urbana, now synomymized with C. longicaudata) is uniformly gray; both of these species are about 15 mm - almost twice as large as the Firebrat
other species of Lepismatidae are normally found outdoors
also see Bristletails (order Microcoryphia), which are able to jump, and have a number of other differences
