The catch in a Nzi trap baited with cow urine and acetone in the Kenyan Rift Valley in June 1997. The netting contains 1,700 horse flies, stable flies and tsetse that have entered the trap within the last few hours. The collecting bag and bottle are overwhelmed by a catch over a few days of about 20 - 30,000 flies
