Like all insects, its body is divided into a head, a thorax, and an abdomen. In doing so, they cause considerable hypoedrma. Goats and sheep are occasional hosts, but development is not completed in these hosts. Eggs are about 1 mm in length, slender, and white in color.

Little is known about communication and perception between warble flies other than that they have keen eyesight. Nutrients are transported across the larval body wall into the hemolymph.

Animals with bilateral symmetry have dorsal and ventral sides, as well as anterior and posterior ends. This is more successful when the larvae are mature.
