Aleochara bilineata is a species of rove beetle that lives in sub-tropical and cold tolerant climates throughout the world. This beetle was first biologically described by Wadsworth in 1915. It is used by humans as crop pest control due to the variety of pests it consumes, including caterpillars, mealybugs, mites, maggots. These beetles have a larval phase that occurs over the winter and an adult phase that emerges in the spring. They are often found in moist environments, in compost, or near crops.
