As anyone who’s been following these blogs will know, we still haven’t found the cicada. But that doesn’t mean that it isn’t still there in some as yet undiscovered spot. In 2016, as well as the existing approach with the CicadaHunt smartphone app, we’ll also be deploying small low cost cicada detectors. These combine a small low-power microprocessor and a sensitive microphone, and are capable of detecting and recognising the high frequency calls of the cicada. We’re hoping to deploy 100 of these detectors at prime spots in the forest (sunny south-facing clearings). The detectors originate from a large project (www.soundtrap.io) to develop low-cost open-source acoustic tools for biodiversity monitoring, and we’re really excited to be able to try them next year.
