In the course of other studies in large-scale calf units in Czechoslovakia, it was noticed that relatively large numbers of adults of Hydrotaea armipes (Fall.) alighted on the watering eyes of calves, both in the paddocks and in the building where the animals were housed. The flies were active throughout the day when the temperature was above 12 deg C. The activity of the females in the buildings was directly proportional to that of females in the paddocks; the numbers of active females indoors were 0.08--17.3% of those active at the time in the paddocks. The flight range of females from the buildings or from the paddocks was no more than 10--20 m. It is assumed that the alighting females orientated visually at distances greater than 5 m and chemotactically at lesser distances from the calves.
