Dear Mike, congratulation for this nice development! I understand from your description that you focus on adults, but I didn’t clearly understand if the device is set underwater or close to stream to focus insects flying in the vicinity. Regarding your concern about insects being too close from the camera lens, was it finally a frequent issue? We developed an underwater camera trap originally targeting amphibians, but many sightings were actually insects (attracted by visible light). In our case the specimen (amphibian, insect…) has to enter within a tunnel of about 4 cm of diameter at a distance of about 10 cm from camera lens. By this mean the specimen is always placed at a defined distance which is quite helpful for standardising images for automated treatment. Here some more sample of observations https://wildlabs.net/discussion/underwater-camera-trap-call-early-users
