silverfish and earwigs
Silverfish is a small, wingless insect, light gray and blue in color, and has fish like movements. These insects are nocturnal and typically 13-25 mm long.
Earwigs: Most earwigs are flattened (which allows them to fit inside tight crevices, such as under bark) with an elongated body generally 7–50 millimeters (0.28–1.97 in) long. Most earwigs are nocturnal and inhabit small crevices, living in small amounts of debris, in various forms such as bark and fallen logs. Species have been found to be blind and living in caves, or cavernicolous. Food typically consist of a wide array of living and dead plant and animal matter.
