How Did Silverfish Evolve?
WouterSilverfish are insects, and like most insects, they are not venomous to humans. However, a silverfish infestation can cause damage to your home. You can find these insects in kitchens, basements, and bathrooms.
They are nocturnal, meaning they live during the night. They prefer dark, moist areas. In order to survive, they need to be sheltered from direct sunlight. Silverfish are cosmopolitan species that live in the Nearctic biogeographic province, which includes North America south of central Mexico and Greenland.
A silverfish’s lifespan is between two and eight years. Its molts occur frequently. Some species may undergo as many as fifty molts in their lifetime.
Silverfish are nocturnal, which means they are active at night. Their preferred habitat is in damp, dark places, such as attics and basements. If you are lucky enough to live in a house with an attic, you might be able to spot a silverfish.
Although the exact origin of the silverfish is still unknown, scientists believe it has evolved from a marine crustacean. The earliest fossil records of silverfish are from Cretaceous amber. Later, in the late Silurian period, the insect evolved into its present form.
The name “silverfish” comes from its shiny, metallic appearance. As they age, silverfish develop a grayish color. While they are young, the nymphs are creamy white.
Silverfish have a round head and a pointy abdomen. Their antennae are long and curved. Each appendage has three bristles, which are located on the rear.
