These methods also capture and kill the insects. To noninvasively monitor the spatial distributions of flying insects, we developed and implemented a scanning lidar system that measured wing-beat-modulation. Transmitting and receiving optics were mounted to a telescope that was attached to a scanning mount. As it scanned, the lidar collected and analyzed the light scattered from insect wings of various species. Mount position and pulse time-of-flight determined spatial location and spectral analysis of the backscattered light provided clues to insect identity. During one day of a four day field campaign at Grand Teton National Park in June of 2016, 76 'very likely' insects and 662 'somewhat likely' insects were detected, with a maximum range to the insect of 87:6m for 'very likely' insects.enInsectsOptical radarBiogeographyThesisCopyright 2017 by Martin Jan Tauc
