The main differences between drain flies and fruit flies lie in their physical characteristics. Both types of flies are approximately one-eighth of an inch in size, but they can be distinguished by specific features. Drain flies have fuzzy wings, prominent antennae, and typically exhibit black or brown coloring on their bodies. They are commonly found near drains, hence the name. In contrast, fruit flies have distinct red eyes and bodies that can range in color from brown to yellow. They often have dark stripes or spots on their bodies. Fruit flies are attracted to ripe or decaying fruits and vegetables, as well as other organic matter. While drain flies and fruit flies share similarities in size, their wing appearance, antennae, and body coloring are distinguishing factors. Understanding these differences can aid in identification and implementing appropriate control measures if necessary.
