English: Example of a video record used to quantify the biting responses of G. pallidipes. The holding cage was slid from an acclimatisation airflow at 24.5°C, 7.3% RH to a test airflow (red light on) where the female was exposed to an increase of 13.1°C and 72.4% RH. The fly responded by regularly passing its haustellum through the cage netting. Latency is the time between the moment the red light turned on and the onset of the first bite, i.e. the first time the haustellum crosses the netting. To limit the size of the file only 22 s of the high resolution video record is shown.
