Data for a field experiment on remote sensing of flying insects are supplied. A bistatic CW lidar system of the Scheimpflug type was employed, and echoes from flying insects over and close to a Swedish lake were recorded as read-out files from an array detector making observations along the emitted laser beam. The activated pixels of the detector could be converted into range data by triangulation. With a high detector read-out frequency, data on numerous insects could be obtained. Special emphasis was put on distinguishing between large and small insects (from the intensities of the recorded echoes) and the insect positions with regard to the shores of the lake. 

Data were recorded by using a CW Scheimpflug lidar system equipped with a linear array detector. Insect echoes, recorded by the detector are read out at a high repetition rate. The provided material constitutes the raw data used to produce the evaluated material, which is displayed in the publication figures.
