This from the AthensNews website in Athens, Ohio, which is at Brood V's Ground Zero so to speak. Dated April 27, 2016. Author, Dennis E. Powell.

Quoting Dr. Gene Kritsky:
"...not uncommon to find up to 200 per square yard."
"People will begin to notice the 'chimneys' that occur [at the ground surface]. Under their decks or in covered areas, [people] will notice what look like little crayfish chimneys. But that's the cicada nymphs building these extensions to their [underground] tunnels."

"The females do flick their wings [see previous post on the noise mimicry of snapping one's fingers] in response to a male, so the males [the noisy critters] will start walking towards her."

"When they emerge, they're food for all sorts of animals -- in 1999, the [Ohio] Division of Wildlife reported that the average weight of male turkeys from eastern Ohio was higher than it was the previous year."

[Why did the turkey cross the road? To gorge on cicadas?]

Dr. Kritsky described, on the other hand, an over-enthusiastic Labrador Retriever dog. [Reporter] At first, the dog was playfully snatching the cicadas out of the air as they flew by. Dr. Kritsky: "When I saw the dog again 48 hours later, it was on the porch, its head down, and cicadas were actually landing on it." 'But no permanent harm was done.'

And you know what else can happen?

"That certainly does happen," says Dr. Gene Kritsky. "Briggs & Stratton weed whackers and certain kinds of lawn mowers vibrate at the same sound as a cicada chorusing sound. And that causes other cicadas, males and females, to fly towards that sound, because they think that it's a congregation of other cicadas for possible mating."
[Reporter] As a number of YouTube videos demonstrate, the phenomenon is not limited to weed whackers and lawn mowers, either. It's been shown to happen with electric saws, drills, and angle grinders. This year we'll find out if cicadas are drawn to hobby drone aircraft. Those didn't exist, in 1999, when the Brood V periodic cicadas last emerged. [Endquote]

Last but not least:
If the soil where these periodic cicadas have spent the last seventeen years has high levels of mercury -- any levels of mercury actually -- so have the cicadas, according to Dr. Kritsky and other cicada entomology specialists. Do you cicada-cookers want to eat mercury this summer??
