Cicadas may have just emerged, but they spent seventeen years underground. That means they are old enough to drive! I took this one to get it's learners permit last week even though I doubt it will live the nine months required to get it's provisional license.

One of the first things that is being done for the Amalyn Bethesda housing development is to connect Greentree Rd and Greyswood Rd. They have started clearing trees at the end of Greentree Rd to allow for this work to start.
Here is how Greentree road looks now. All the trees and brush has been removed.
This is from the field, looking at the dead-end of Greentree Road. Prior to this, the trees and brush were dense enough that you couldn't see Greentree from here.
For comparison, here is how the end of Greentree Road looked earllier this spring.

"In the Spring a young man's fancy lightly turns to thoughts of love." (Alfred, Lord Tennyson)
Now that the cicada's have been out a little while, and the racket they make has grown increasingly loud, it should come as no surprise that the singing is starting to pay off, at least for this lucky fellow and equally lucky lass. They are especially lucky that no one stepped on them while they lay in ecstasy on the sidewalk.
After spending today listening to the cicadas, I was a bit surprised tonight to not hear them.

Not everything is complete, there are a couple of places where the trail has been torn up and needs to be replaced, primarily at Albermarle St, the ramp leading to one of the bridges, and the area where the rebuilt a drainage creek that goes under the trail. After that, everything will be back to normal, but as of now, as long as you don't require handicap accessibility it is fully usable.

Here are a couple of videos I have taken of the cicada attack.
This first video is a time-lapse of a Brood X cicada molting on a blade of grass. This time-lapse was taken over a period of about 2.5 hours one night. One picture every 15 seconds. Where a cicada walks over the emerging one and where the emerging cicada flips so it is holding onto its shell I have duplicated each photo 4 times to slow it down and make it easier to see what is happening.
This next video isn't a time lapse, it is just a view of about 20 cicada nymphs crawling aimlessly through the grass. I was taking a timelapse of a molting cicada at night so had a couple of lights turned on, it appears the nymphs are attracted to light.

These Brood X cicadas have been underground for 17 years, but now they are climbing out and onto trees and plants. Once out, they do a final molt to their winged form. They will only live for about a month longer during which time they will mate and lay eggs.

I took this timelapse video of a couple of cicada nymphs molting and their wings expanding. One cicada starts molting then another climbs on top of it and also starts molting.

When the WMAL radio towers were here they were grounded with copper radiating out from each tower. I believe these copper straps were what was used. They are buried several inches under the soil and go nearly to the edge of the property. Many of them have been pulled out and in a couple of places parts of the straps are lying on the ground.

I was walking around Bethesda, MD this morning and noticed the first advance troops of cicadas on the trees. They weren't everywhere, some trees would have a dozen or so, others just a couple, but most trees didn't have any yet. That will change in the coming days.
When they start coming out en-masse scenes such as this will be common. Here you have a few cicadas still emerging from their exoskeleton and a couple who have just finished emerging but whose wings are still wrinkled up.
As they rest, their wings expand to full size. Notice they are very pale, it takes them a few hours to darken and for their bodies to harden.
