Abstract
Female black flies were taken abundantly in fan traps, on "sticky" mannequins, and on "sticky" flesh-colored paper cylinders when carbon dioxide was released beside them, but few were taken without the carbon dioxide. More flies were taken from the cylinders placed horizontally than vertically and more from the ends of the horizontal cylinders than from the mid-portions. More flies landed on the ends of the vertical cylinders near which the carbon dioxide was escaping than on the opposite ends. Many flies were collected using human breath as a stimulus. Heating the silhouettes did not predictably affect their attractiveness. The combined results indicate that carbon dioxide and vision are especially significant to the orienting and landing of Simulium venustum.
