I would just like to put on record that we have successfully tested an AudioMoth recording "bug" in a local garden inside a plastic bag whereby it recorded the buzz of nearby bees, along with everything else! We ran the recordings through our BEESWAX7 buzz identification and counting program and the following results were recorded from a bed of lavender in overcast-but-warm conditions:

Pratorum (bumble bee) = 1
Terrestris (bumble bee) = 39
Mellifera (honey bee) = 3
Haemorrhoa (mining bee) = 1

I have not run the de-duplifier program so there may be a little "Loiter inflation", particularly on Terrestris? Tally ho! Andrew.
