Silverfish

Hopefully, it is ok to quote a QuestaGame expert (29/6/2016): It may take up to two years for silverfish to become adults. Silverfish can withstand long periods of starvation. Some specimens have been reported to live 307 days without food. The female silverfish lays between 50 and 150 eggs during her lifetime. The eggs are laid singly or in small groups and are either randomly distributed or in concealed places near food. The eggs hatch in three to six weeks depending on temperature. The first nymphal instar lasts seven to 10 days and successive molts occur every two to three weeks depending on temperature. https://www.bookstore.ksre.ksu.edu/pubs/EP123.pdf This particular one, we believe is a nymph of Ctenolepisma lineata: "The abdomen is often marked with 4 dark brown lines. Generally similar to the closely related Common Silverfish (Lepisma saccharina) but can be distinguished by being rather stouter and less shiny with all appendages (antennae and 3 "tails") noticeably longer. The young are light brown, and are often tinged with pink until the fourth molt, which occurs a month or so after hatching."
