Face Fly

Face flies resemble the house fly, but may be slightly larger and grayish in color. Face flies have 4 stripes on their thorax and sponging type mouth parts like the house fly. Females look very similar to the house fly, while male face flies have abdomens that are yellowish-orange in color. Female face flies lay eggs only on fresh, undisturbed cattle manure and are primarily considered a pastured cattle pest.
