What is a common feature of booklice?

Booklice are small, wingless insects that typically measure less than 1/16 inch long. Their lack of wings is a defining characteristic, which helps them thrive in a variety of habitats, particularly in damp or humid environments where they feed on mold and decaying organic matter.

The other features mentioned, such as having wings, being bright red in color, or being large—over 1 inch long—do not apply to booklice. They are generally pale or translucent, making them less noticeable, and their small size does not surpass the 1/16 inch mark. Understanding these characteristics is essential for identifying booklice and distinguishing them from other types of insects.
