Evening Republican, Volume 59, Number 69, Rensselaer, Jasper County, 23 March 1917 — "Fly Time." [ARTICLE]

"Fly Time."

Dr. F. A. McDennoth has observed the oddities in the behavior of houseflies. They have a strong tendency to go with air currents between 80 and 100 degrees. This explains why flies are so bad in hot weather, when it -is about to rain. , Tfie heat usually ranges upward toward 100, and the air travels along too slowly to cause the vapor in it to evaporate. The heat, humidity, and slow movement of the air gives the housefly its “fly time.” As pests, they are then in their glory.
