Generalized Life Cycle of A Silverfish

Silverfish Life cycle


There is basically three phase in a Silverfish’s lifecycle. A brief description of Silverfish’s life is as followed from egg to adulthood:

  • Egg: Life of a silverfish begins with oval shaped tiny egg. These eggs can be found in dark, damp places in areas like the basement, sink, old boxes etc. These eggs are laid in a group of two hundred approximately. When the weather condition and temperature are ideal for a baby silverfish, then they hatch the eggs. This process can take time from one to two weeks. If the temperature falls below 10 degree Celsius, silverfish egg can lay asleep till the weather gets warmer. Proper temperature is very necessary to speed up the process of developing life from an egg.
  • Nymph: Newly born silverfish are found in pink colour. It takes several weeks after hatching to get the silver colour and other characteristics. Once they got in silver colour, it can be said the nymph got the appearance of young silverfish. Silverfish continue moulting to an approximate size of three to four inch. Their diet is basically starch and protein food. So they can damage your books, papers, clothes and stored food in order to grow up.
  • Adult: In the span of a few months, when the temperature is favourable, the silverfish grows from egg to sexually mature adults. However, if the temperature is not favourable, and remain cold, then it can be from one to two years. Silverfish are counted in those rarest families of insects, who continue to moult even after reaching the complete maturity. The male and female silverfish reproduce by touching their antenna. This procedure can go long up to thirty minutes to one hour. A female adult silverfish is capable of producing more than one thousand eggs in their whole life. Adult silverfish can live up to three years in ideal weather condition and temperature.
