The purpose of this study was to determine if the numbers of insects infesting cattle droppings were consistently abundant at some farms and rare at others and, if possible, to disclose what factors might be responsible for these differences in abundance. Factors considered were: The interaction of insect fauna in the droppings; weather; size of the herd; density of the cattle populations; condition of the pasture and insecticidal treatments of the cattle. Although particular attention was placed on the face fly all insects infesting cattle droppings were taken into account.

It was considered that some insight on the nature of factors involved might be obtained by consistent sampling of droppings from farm to farm. Samples of cattle droppings were collected weekly from May through October, 1963 near Lincoln, Lancaster County, Nebraska.Droppings were taken from eight farms within 16 miles of each other.
