Lepismatidae
Lepismatidae is a family of primitive wingless insects with about 190 described species. This family contains the two most familiar members of the order Zygentoma: the silverfish and the firebrat. It is one of five families in the order Zygentoma.
Lepismatids are elongated, flattened insects, the majority of which are scavengers. The abdomen is usually clothed in tiny scales and terminates with three "tails" of roughly equal length. The compound eyes are small and well separated.
They typically live in warm, damp environments, including indoors. They avoid light.
Parasites
The following Strepsiptera species are known to parasitise Lepismatidae: Eoxenos laboulbenei on Lepisma aurea, L. wasmanni and L. palmonii; Mengenilla parvula on Ctenolepisma michaelseni; Mengenilla nigritula on C. ciliata and Ctenolepisma sp.; Mengenilla laevigata, M. quasita, M. spinulosa and M. subnigrescens on C. lineata; and an unidentified species of Strepsiptera on Mormisma peyerimhoffi.Parasitic Apicomplexa are often found in the intestinal tract, especially the crop, of Lepismatidae. Ctenolepisma lineata contains on average 15 parasite specimens per animal. Several species of gregarine parasites have been recorded from the intestinal tract of the gray silverfish:
