These were about the size or mice or bigger... maybe even gerbils? 3-4 inches long probably.
To give you a perspective, I was able to catch an ANT as it crawned over the bugs head... that's a regular sized ant, barley on it's eyeball.
Pretty freaky, not a huge fan of bugs, but oh well. I think these might be the Mormon Cricket things that eat the crops... (which are in turn eaten by the California Seagull, hence the Utah state bird being the California Seagull...)
