Appearance
H. irritans is the smallest of the biting muscids, gray in color, approximately 3⁄16 in (4.0 mm) in length. Both the male and female have slender, black, piercing mouthparts which project forward from the bottom of the head. They often aggregate densely on cattle, each fly oriented with its head in the same direction as hair tips of that site on the host. Horn flies typically have eyes that are dark reddish-brown.

Famous quotes containing the word appearance:
“The whole appearance is a toy. For this,
The dove in the belly builds his nest and coos,
Selah, tempestuous bird. How is it that
The rivers shine and hold their mirrors up,
Like excellence collecting excellence?”
—Wallace Stevens (1879–1955)
“Do not look on his appearance or on the height of his stature, because I have rejected him; for the LORD does not see as mortals see; they look on the outward appearance, but the LORD looks on the heart.”
—Bible: Hebrew, 1 Samuel 16:7.
“This mesa plain had an appearance of great antiquity, and of incompleteness; as if, with all the materials for world-making assembled, the Creator had desisted, gone away and left everything on the point of being brought together, on the eve of being arranged into mountain, plain, plateau. The country was still waiting to be made into a landscape.”
—Willa Cather (1873–1947)
