Bugs Matter vs OpenBat

The number of insects has been falling at an alarming rate for many years. It's no exaggeration to say that unless something is done to halt the decline, our own future could be at risk. Patterns and trends in insect numbers are nuanced, however, and we still don't have that much information on the relative rate of decline over time, and there are too few studies looking at this problem. The Bugs Matter app is an application that enables you to get involved in this critical biodiversity monitoring. Splatted insects are an unfortunate by-product of our habitual use of vehicles, but also presents us with a prime way of monitoring them. With Bugs Matter you can contribute counts of insects and other ‘bugs’, along with the route of the journey you make in a vehicle. You can also provide details about the vehicle used (needed for data analysis) by entering the registration number. This will provide scientists with important new information that will contribute to conservation, evidence, planning, and education. Anyone with a phone and use of a vehicle can get involved with recording insect counts. It is very easy and quick to submit useful data without specialist knowledge. You do not need to be the driver of the vehicle in which you make a journey. Take action for insects and help us to study this important subject!

OpenBat is a free iOS app that turns a compatible ultrasonic USB microphone into a live bat detector. It captures audio at up to 384 kHz, shows a real-time spectrogram, detects individual echolocation pulses, and, where an open-source model exists for your region, suggests species IDs on-device. Currently covers the US and Canada, with UK/Europe in beta. ** Bat detection requires an external ultrasonic microphone. Visit OpenBat.app to learn more. ** Hear bats in real time OpenBat uses two ways to turn ultrasonic bat calls into sound you can actually hear: - Heterodyne: tunes into a band of frequencies and scales it down. Preserves rhythm and loudness, but can sound clicky. - Time expansion: records a call, then plays it back at a fraction of the speed. Preserves the character of the call, but not the rhythm. - Het + TE hybrid: both running at once. Analyse your recordings Record what you hear, then break down the calls in Playback. Extract the parameters used to identify species, save them for later, or post recordings straight to iNaturalist for the community to help confirm an ID. Learn about bats AutoID suggests which species might be around you in real time. The Field Guide covers bats in your area and worldwide, curated by bat experts and kept up to date — and if you know your local bats, you can contribute too. Share it, or keep it to yourself Play the bats you're hearing through your device's speakers, or plug in headphones and listen alone.
