Mark-recapture studies were conducted in a 41 square km agricultural research center near Mead, NE, in June, 2002 and 2004. Piles of cattle-manure contaminated hay debris were dusted manually with Day-Glo fluorescent powders, and marked flies were captured subsequently with transects or grids of sticky traps in the surrounding landscape. Captured flies were ca. 40% female, and virtually all were previtellogenic nullipars. Spatial distributions indicated rates of spread outward from the point sources were 0.060.08 square kilometers per day.
