Silverfish are nocturnal, flattened insects typically 13–25 mm long. Their body tapers at the end, giving them a fish-like appearance. The newly hatched are whitish, but develop a greyish/silver colour with a metallic shine as they get older. Silverfish completely lack wings, they have long antennae, and move in a wiggling motion that resembles the movement of a fish. Silverfish typically live for two to eight years.
