This post is really interesting. Just yesterday I was taking the sheets off the line and there was this huge thing clinging to the top sheet. I ran to get my DH and I grabbed a glass jar and caught it. We both thought perhaps it was a cicada. I looked it up on the computer and sure enough it was. We were in Indiana a few years back when they were so thick: all you could hear was their loud noise from the time you went outside until nightfall. Hope they don't get that thick here. Never heard of a cicada wasp. Thanks so much for this info.
