Bristletails are small, wingless insects belonging to the order Thysanura. They are characterized by their elongated bodies and three long, tail-like appendages at the rear. Commonly found in damp environments, they thrive in leaf litter, soil, and under rocks. These insects are known for their unique movement, which involves rapid, jumping-like motions. Bristletails primarily feed on decaying organic matter, making them important decomposers in their ecosystems. They are often mistaken for silverfish, another wingless insect, but can be distinguished by their longer tails and different body shape.
