Very interesting, Nancy. Do you or anyone else know of any guides to the
identification of insect sounds?

Subject: [Naturens] Grasshopper Mating Flight
Here is a couple of phone videos of two grasshoppers doing their mating
flights- a very common sight here on all sunny days lately. I have not had a
chance to get a good look at the insect for ID but it is a dark grasshopper
and possibly a Crackling Forest Grasshopper (love the name!) aka
Trimerotropis verruculata based on range and habits. The genus is probably
correct at least. I read this group can be distinguished acoustically.
Please zoom in and turn up the volume for both:
The first short clip is easier to see and shows one once it got the clicking
underway.

This second short shows the pattern- they always start off hovering with
silent wings and then turn on the clacking and finally drop to the ground
where I can never locate them for a photo.
