Fish moths, also known as silverfish, are primitive wingless insects with soft flat, spindle-shaped bodies. They have a shining silver appearance due to tiny overlapping scales that easily rub off. They are nocturnal and find their way in the dark by means of their long antennae and other appendages.
Fish moths feed on dry organic material and are often found in old books or documents doing their own type of destructive editing. Some species also live in ant nests and under organic material and stones.
