I'll be attempting to build this over the winter: http://recordinghacks.com/articles/h...-a-microphone/
The Panasonic WM-60AY that they used is not being manufactured anymore apparently, however I understand the WM-61A is the replacement for it.

As you can see from the datasheet the frequency response is flat. Furthermore (what I find the most attractive), the capsule has a very small size of 6mm at the biggest dimension. I have L-shaped hive entrances, so coming from the front will unlikely yield good results. I envision the capsule mounted on a metal rod / pipe that can be inserted through a hole from the back (approx. 10mm) drilled in the rim of the bottom board. If not in use, the hole can be plugged with a M10 or similar bolt. I already use a similar approach to insert my oxalic acid vaporiser and it works great.
How to connect it to a phone etc. remains to be seen, but I expect to need a pre-amp of some sort.
I realise that it is unlikely to get support from the BHG team for understandable reasons. Wish me luck, I'll need it :-)
