Close-up of tympanum on right front tibia. Isn't this an odd place to have an "ear"?

Re: Odd place for an ear
Thanks, Patrick, for posting these enlightening photos!
I don't know how "mobile" (i.e. flexible in positional orientation) their front tibiae are, but I could see how being able to easily aim your auditory sampling organ in all sorts of directions could be very helpful. For instance, in finding a calling mate...especially for crickets, which seem to be such good ventriloquists!
In addition, having a narrow "central directional-cone" of increased amplitude sensitivity would really help narrow down the source of a sound. I guess the stereo effect of having two ears helps a lot. But I wonder to what extent bats...with their often very specialized sound-focusing ear lobe shapes...are also able to move those ear lobes to pin-point sound sources?
[Imagine having an narrow-focusing ear on the back of one's wrist...would really help
me
locate crickets! ;-]
