Allers play important roles in ecosystems, including pollination and decomposition. These insects are often attracted to food sources and can be found near decaying organic matter. Some species of allers are known to be pests, while others contribute positively to their habitats. Their life cycle includes stages such as egg, larva, pupa, and adult, similar to other members of the Diptera order.
