In addition to detecting bats: I occasionally do enjoy detecting, and attempting to identify Orthopetra (various singing insects). I'm going to try to keep this post as brief as possible. I simply want to share the results of tests I've done; using a few different bat detectors, etc.
For those who are also interested in singing insects, there are two books that I can highly recommend:
The first is 'Guide To Night-Singing Insects Of The Northeast' by John Himmelman.
The second, is called 'The Songs Of Insects' by Lang Elliot and Wil Hershberger. They both cover the Orthoptera of the Northeastern United States.
In the US, they may be found just about anywhere books are sold.
For Readers in the UK & Europe who are interested, they may be purchased from NHBS, by clicking on the links below:
Happy bat (and bug) detecting!
