Description: The newly hatched silverfish nymphs look exactly like tiny adults, and therefore it is known that these are insects that undergo simple metamorphosis
Biology: Silverfish, depending on the species, can lay from 1000 to 3000 eggs over a period of two to five years. The eggs hatch anywhere from three weeks to two months.
Habits: The main damage done by silverfish, inside of homes or other structures, is damage to paper goods, they feed on starches. They may feed behind wallpaper on the starchy paste used to glue it to the wall, or in the bindings of books on the dried glue they can find there. Old documents composed of parchment or other starchy paper can be ruined, along with family pictures that have been stored away. Silverfish are not new on the scene, and in fact are some of the most ancient of insects.
