Often solitary, Gray Silverfish are usually spotted indoors, scurrying around floors and up walls, looking for a warm place to rest.
The Gray Silverfish is a fast insect usually found around dark, warm places inside a home (ovens, furnaces, fireplaces, bathroom vents, clothes dryer). It has a very flat body and can run under baseboards and into other tight spaces to hide. It has three thread-like tails found at tip of its abdomen that almost match the length of their antennae. Silverfish bodies are covered in flexible and slippery gray scales that help prevent the insect from capture by bigger things like centipedes and spiders.
All Silverfish are attracted to dry, starchy substances, which comprise their food. It is not unusual to find them wandering around in pantries or cupboards where bags of flour, sacks of potatoes, and other starchy delights are stored. The crusty glue that binds old book pages together is also source of food to Gray Silverfish so it is common to find them in libraries, both public and at home. It is also not unusual to find them even between the pages of old books. Gray Silverfish can live for months without eating. They are harmless to humans, though many people consider them a nuisance. This type of insect requires a long time to mature. Some Silverfish need 2 years to become fully-grown adults, and other species take even longer.

Grayed-out selections indicate that the subject in question has not been reported in that particular territory.
