Another interesting find:

I was our for a weekend walk in the local cemetery with the family, and we came across thousands of these large (more than 2 inch) bugs crawling along the ground; there were so many, that hundreds were crushed on the cemetery roads - even though there were very few cars.
My son and I kidded each other about picking them up, but they were so large and ugly we weren't seriously tempted. I had no idea what they were ...
Turns out not picking them up was a good idea - they are American Oil Beetles, one of the "Blister Beetles", and they are highly toxic; they exude an oil (hence the name) from their limbs, which creates big, painful skin blisters if handled.
So if you see one - don't touch it. And definitely do not eat it, they are very poisonous.
