Alan,

The Edutige mic looks intriguing.  I had a listen to a sample
recording but it seems to me that the hiss-noise increases along with
the stronger signal from the mic, so it is not doing much more than
amplifying the sound you are already getting from the iPhone.  All
the same, such gadgets can be useful to documenting wildlife sounds
if nothing else is available.  You would probably find the windshield
is inadequate, but better than nothing.

If you want to use a larger better quality mic you have to consider
handling noise and most likely you would need a handle and shock-
mount for it, and a decent wind cover such as one of the 'softie'
types.  By the time you have all of that (e.g. Sennheiser ME66 gun
mic is a great field mic for species recording), then you might as
well go with a purpose-built recorder such as Sony or Olympus or
whatever (lots of references on this list), and you can then set the
recording sample rate to 96 K which will be useful for insect
recordings.

Meanwhile, you can probably do quite a lot with the iPhone and it
would be no worse than the equipment that many of us started out with
e.g. hissy cassette recorders and tie-pin microphones.

good luck!

Vicki
