Could I find a grasshopper species classification key?

Question

I know it's probably hopeless (since there are so many species of grasshopper out there), but I was wondering about the many grasshoppers in my backyard, and if I could possibly find out what species they are. I've looked for something like that on like bugguide.com or something like that, and different places like that. Anyone know where I could access what I'm looking for?

Answer 1

On bug guide there is a list of books they use for their identification.  I will let you search the list to find what you need.

http://bugguide.net/bgref/all

I found it by going to the site map looking for references.

Answer 2

I hope these are useful -
