Jerusalem Cricket/Potato Bug

Hello! Thanks to your website, I was able to identify a bug I’ve seen several times in my life, and seriously creeped out by.
I clean an elementary school in a rural area, and always find them in the tiled bathrooms far from any outside doors. I wonder what it is they are looking for…water? Somewhere cool?
These are very hearty creatures I have also discovered. One time, visiting in the Sierra Mountains, I got up in the morning to put on my shoes. A bit later I realized I had a rather uncomfortable rock in my shoe, but was unable to stop what I was doing to remove. Roughly half hour later, I pulled off my shoe and slapped the heel into the palm of my hand catching a really angry Jerusalem Cricket. I then promptly flipped out completely, flinging the insect in the air and released a piercing scream. I was completely taken by surprise something that size survived under my foot. Since that day, I have to say, it’s been on my mind what that insect was.
Thanks again for the great site with the awesome information!

Great Grig

Hi Corey,
Jerusalem Crickets and your insect, a Great Grig,
Cyphoderris monstrosa, are all in the same suborder Ensifera, the Longhorned Orthopterans, but they are in different families.  The Great Grig has a much more limited range, as it is only found in the Pacific Northwest.  According to BugGuide, Great Grigs are found in:  “coniferous forests containing Lodgepole Pine, Englemann Spruce, and Mountain Hemlock; adults hide beneath leaf litter during the day, and become active at night, climbing tree trunks and continuing high into the branches to feed, sing (males), and mate.”

    Haha, my room is in a 100 year old basement. I just recently found one of these guys for the first time. Good to see I’m not the only one freaked out by the size of these buggers.
