Silverfish are sometimes mistaken for centipedes, which do inflict painful bites. One way to tell the difference is to note how many legs the bug has. Upon close inspection of a silverfish, youâll see that it only has six legs. o Silverfish are small insects (between 1/4 inch and 1/2 inch) and have shimmering, silver-colored scales.
Silverfish are nocturnal insects typically 13â25 mm (0.5â1 in) long. Their abdomens taper at the end, giving them a fish-like appearance. The newly hatched are whitish, but develop a greyish hue and metallic shine as they get older.ike other species in Apterygota, silverfish are completely wingless. They have long antennae, and move in a wiggling motion that resembles the movement of a fish. This, coupled with their appearance and silvery scales, influences their common name. Silverfish typically live for two to eight years.
