Predicted profiles of insect numbers within 10 m height intervals in a stably stratified nocturnal boundary layer, (a) 2 hours, (b) 4 hours and (c) 8 hours after climbing to 150 m and thereafter responding to gusts in vertical wind speed by climbing or descending in a direction opposite to the gust with a vertical airspeed of wf=0.3 m s−1 when the vertical wind speed exceeds wc=0.1 m s−1. The stable boundary layer has height z=200 m.
