Sadly, the mystery has not been solved about those vein like things on the underside of my june bug. They may be fungal in origin according to the curator of zoology at the local museum, but he would need a look see at the animal itself. That isn't possible as I set the critter free the next morning.
I did take some pictures today, though of some lady bugs (ahem) doing it.
Nothing like having the word p*rn in your blog post title to drive up readership....
