barkflies

Barkflies, also known as Psocoptera, are a small order of insects. They are typically found in damp, dark environments such as under bark, in leaf litter, or in decaying wood. Some species also inhabit buildings, particularly in areas with high humidity. Barkflies are characterized by their relatively small size, often less than 6 millimeters in length, and their soft bodies. They possess chewing mouthparts and long, thread-like antennae. Their wings, if present, are typically held roof-like over their bodies when at rest.

The diet of barkflies varies depending on the species. Many feed on algae, fungi, lichens, and decaying organic matter. Some species are known to consume mites and insect eggs, while others may feed on stored food products. Their role in the ecosystem is primarily as detritivores, contributing to the decomposition of organic material. Barkflies are prey for a variety of predators, including spiders, ants, and predatory insects.

Reproduction in barkflies generally involves the deposition of eggs, which are often laid in clusters and covered with silk. The nymphs hatch from the eggs and undergo several molts before reaching adulthood. The life cycle can be influenced by environmental conditions such as temperature and humidity. While some species are considered nuisance pests, particularly in homes where they can infest books and other stored materials, barkflies are generally not of significant economic importance.
