Victor,
the guy who set it up, Troy Bartlett, does phenomenal photography - (I linked his main site below). the really cool thing about his new site is that it is interactive. Register for free and then you can help others i.d. insects, you can recommend books, you can post photos of your own to get help with i.d. or just because you have cool photos! LOL!. I asked him about a forum and he said it is one of his goals.
As for the Utah critter...it is the Mormon Cricket, which is actually a grasshopper. Here's a link: www.aphis.usda.gov/ppq/ispm/grasshopper/ as for feeding cham's...I think that was discussed last summer on the forum when they were out in droves. Not sure what the general consensus was.
see you on bugguide.net
