The Ultimate Guide To Get Rid Of Silverfish
With their shiny, scaly bodies, bristletails closely resemble silverfish (order Thysanura). Bristletails, however, have tube-shaped bodies, while those of silverfish are flattened. The eyes of bristletails are quite large and meet over the top of the head, but those of silverfish are much smaller and are widely separated. And each jaw of a bristletail has only one point of attachment to the head, while those of silverfish and all other insects connect to the head at two points.
Physical characteristics Adult silverfish measure up to 0.4 inches (10.2 millimeters) in length. Their bodies are covered with silvery scales. Geographic range Silverfish probably originally came from tropical Asia the species is now found living with people worldwide. Diet Immature and adult silverfish are fond of flour and starch and are sometimes found in cereal they also feed on muslin, starched collars and cuffs, lace, carpets, fur, and leather. They are also cannibalistic, feeding on molted silverfish skins and dead and injured individuals. Immature and adult silverfish are fond of flour and starch and are sometimes found in cereal they also feed on muslin, starched collars and cuffs, lace, carpets, fur, and leather.

Silverfish and people Silverfish are considered household pests because...
Although the females of some species of silverfish can reproduce without mating, most species require males and females to produce fertilized eggs. Males deposit a sperm packet on the ground, beneath a silken thread. The packet is later picked up by the female. Females lay their eggs inside cracks and between spaces in leaf litter. The eggs are about 0.04 inches (1 millimeter) long and are longer than they are wide. At first they are soft and white, but after several hours they turn yellow and then brown. The larvae resemble small adults. Silver-fish continue to molt, or shed their outer skeletons, throughout their lives and may live for up to six years.
Is a single dorsal fin with 9-15 spines and 9-21 soft rays. The anal fin has 3 spines and 9-13 soft rays. The caudal fin is forked deeply. Color patterns range from blue to silvery blue, with yellow, pink, or red accents. Most species are less than 23.6 in (60 cm) in total length. The single species of Loboti-dae, Lobotes surinamensis, has an oval or oblong and compressed body, a single dorsal fin with 11-12 spines and 15-16 soft rays, an anal fin with 3 spines and 11-12 soft rays, and 17 soft rays in the pectoral fin. The dorsal, anal, and caudal fins are all rounded. The scales are ctenoid. Adults are dark brown or greenish yellow along the back, and silverfish gray along the flanks juveniles tend to be brown and yellow, and are usually mottled. This species grows to about 39 in (100 cm) in total length.

Arthropods were swimming in lakes, crawling on land, and flying through the air long before dinosaurs. In fact, millipedes are one of the oldest land animals on Earth and have been around for about four hundred million years. Insects are more than 380 million years old. Scientists know this by studying their fossils (FAH-suhls), or remains of animals that lived long ago, usually found set into rock or earth. Scientists who study fossils are called paleontologists (PAY-li-un-TA-luh-jists). Paleontologists study fossils to understand how life has developed and changed over time. The location and chemical makeup of fossils helps paleontologists to determine their age. By studying fossils scientists know that some groups of organisms, such as horseshoe crabs, millipedes, silverfish, and cockroaches, have changed very little over millions of years. The process of organisms changing over time is called evolution (EH-vuh-LU-shun). Organisms must adapt in form and behavior to survive in an...
There are four basic types of metamorphosis. Some millipedes and centipedes, as well relatives of insects known as pro-turans, develop by anamorphosis (ANN-eh-MORE-feh-sihs). Their larvae hatch from eggs with fewer body segments than they will have as adults. Additional segments and legs are added as they molt. When wingless diplurans, springtails, silverfish, and bristletails molt, the only noticeable change is that they are larger. They molt many times as larvae and will continue to molt after they reach adulthood. Grasshoppers, true bugs, drag-onflies, and some other winged insects develop by gradual metamorphosis. The larvae strongly resemble the adults when they hatch, but they lack developed wings and reproductive organs. These insects stop molting once they reach the adult stage. Beetles, butterflies, moths, flies, fleas, ants, bees, wasps, and others develop by complete metamorphosis. They have four very distinct stages egg, larva, pupa, and adult. They do not continue to grow...
The term commensalism was first used by P. J. van Beneden in 1876 for associations in which one animal shared food caught by another animal. An example of a commensalistic symbiosis is the relationship between silverfish and army ants. The silverfish live with the army ants, participate in their raids, and share their prey. They neither harm nor benefit the ants.

Other groups of arthropods do not mate directly. For example, male spiders must first transfer their sperm to special containers on their pedipalps before they are ready to mate. They use the pedipalps to put the sperm directly into the female's reproductive organs. Male horseshoe crabs climb on the back of the females and release their sperm onto her eggs as she lays them in the sand. Silverfish males deposit a drop of sperm on the ground and then guide the female over it so she can pick it up with her reproductive organs. Male millipedes, centipedes, scorpions, and other arachnids put their sperm packets on the ground. Then they engage in a variety of courtship behaviors to guide the females over the packets. In some arthropods the females must find these packets without the help of males.
