Here is a photo I took of some firewood that had some kind of wasps in it. It's white oak that sat for six months after I felled it; not exactly on the ground but maybe 2 feet off the ground. Minor limbs kept the bulk of it from resting on the soil.
As always, if you click on it and then right click on it and pick "view" it will open up in a new window and you can magnify it for more detail.
Right now this is my screen background.
