Arrangement and operation of laser illumination system. a Diagram of bed net depicting laser sources directed across the outside (red) and inside (green) of the net side and a camera trained on the sampled area around a hole in the net. Number and configuration of laser fields, sampled areas and holes varied depending on recording session (see “Methods”). b Bed net (black line) and a hole in it (gap) viewed end-on and showing arrangement and approximate spacings of red laser field (outside of the net) and green laser field (inside of the net). Approximate An. gambiae flight profile [14] shown for comparison. c Photograph of flying mosquito captured immediately above bed net in red laser field. Reflected red and green laser lines visible on floor and vertical edge of corner of bed net
