    Silverfish - (Lepisma saccharina)

    Silverfish love a good old book, a warm fire and a nice piece of bread, just like most people.

    Staff Writer (1/18/2014): These little creatures can be found near the dark, warm places of the home (ovens, furnaces, fireplaces, bed, clothes dryer). They have a very unique tapered shape and can appear to be very flat. The most noticeable feature of the Silverfish besides their silver-gray color are the three thread-like tails found at tip of the abdomen.

    Silverfish are drawn to dry starchy substances commonly found in pantries. The glue that binds old book pages together is also appetizing to Silverfish. This explains why they might also be found in the pages of old books, or running around libraries: the printing material used in these items is a food source. Amazingly, Silverfish can live for months without eating. They are harmless to humans, though their presence is usually considered a nuisance.

    Silverfish bodies are covered with flexible and slippery scales that protect the insect from capture from larger insects such as spiders. This body covering also allows them to neatly fit within the binding edge of a closed book and feed on the paste.

    Another interesting facet about these critters is in the time that they take to mature. Southern Silverfish can see adulthood in 24 months whereas Northern-based Silverfish will take longer. No doubt this is due to the warmer temperatures of the Southern states.

    BUGFINDER: What Kind of Bug is This...
    BUGFINDER allows for a quick search of the Insect Identification database by selecting primary color, secondary color, number of legs and the territory / state in question. If only one color is present on your insect, select it again as its SECONDARY color. Remember that the more details you can offer, the better your chances of finding a match. As a rule of thumb, six legs are typical for most insects whereas spiders generally have eight legs.
