Description

• Ctenolepisma longicaudatum, commonly known as the long-tailed silverfish, is a wingless insect in the family Lepismatidae. It has a flattened, elongated body covered in silvery-grey scales, long antennae and three distinctive tail-like appendages at the rear. It resembles the common silverfish but generally has longer appendages and a more mottled appearance. It moves quickly and is primarily active at night.

Range

• Ctenolepisma longicaudatum is native to Africa but has spread widely through human transport and now occurs in many parts of the world. It is associated with human settlements and is present in Zihuatanejo, Guerrero, Mexico.

Habitat

• This species is commonly found indoors in homes, offices, warehouses and libraries, particularly in dry environments. It hides in cracks, wall cavities, storage areas and behind furniture, and can survive in conditions drier than those tolerated by many other silverfish. It is frequently transported in cardboard boxes, packaging, books and other stored goods.

Diet

• The long-tailed silverfish feeds mainly on starchy and carbohydrate-rich materials, including paper, cardboard, book bindings, glue, flour and food crumbs. It may also consume textiles, dead insects and other organic debris. Although it can damage stored materials, it is generally harmless to people and pets.
