Interesting facts about the silverfish

  • The silverfish or Lepisma saccharina describes an insect, which is counted to the order of the Zygentoma, the Urinsekten and the earth already for over three hundred million years settled.
  • It occurs worldwide, but is found almost exclusively in human dwellings in Europe, where it prefers humid and dark spaces.
  • The silverfish owes its name to its shiny metallic body, which is about an inch long and covered by tiny scales.
  • The silverfish and its nearest relative, the Starfish have no wings.
  • The characteristic appearance of the silverfish is characterized by the long antennae, the broadened breast portion, which increasingly tapers towards the rump, and the two cerci and the middle epiproct, the three bristle-like long appendages on the body end.
  • Silverfish are nocturnal insects that hide during the day in wall cracks, behind wallpaper and joints.
  • They thrive only in high humidity and mild temperatures ranging between twenty and thirty degrees.
  • Silverfish love to stay in bathrooms, toilets and refrigerators.
  • In the wild, they also colonize the nests of some songbird species.
  • Silverfish attract attention through a pronounced mating ritual that begins with the male's dance. If the female shows his willingness, the male weaves a long thread with his sex organ, under which it deposits the seed packet. The female touches the thread, freezes and picks up the seed with her hindquarters lowered.
  • The reproduction of silverfish is not linked to age, but can occur over and over again throughout life, provided that the ambient temperature does not fall below 25 ° C.
  • If the young silverfish have hatched, they develop into adult insects within a few months to years and after a total of eight molts, depending on the conditions of their habitat.
  • Silverfish feed on cellulosic materials as well as on sugars, textiles, adhesives, molds and mites.
  • They themselves serve spiders and earwigs as an important food source.
  • Contrary to popular belief, silverfish are unlikely to be considered pests. However, a heavy infestation may indicate moldy or damp walls.
  • Silverfish do not transmit pathogens and are therefore harmless subtenants from a hygienic point of view.
