Time to start looking for signs of periodical cicadas

Depending on where you live, it might be warm enough for periodical cicadas to start moving around underground, or start digging tunnels to the surface and building cicada “chimneys” above their holes. Report cicada nymph or adult sightings to Cicadas @ UCONN (formerly Magicicada.org) so cicada researchers will know where they are.

What to look for:

1) Animals can hear the cicadas stirring underground, and will try to dig them up and eat them. Look for holes (about the size of a walnut or larger) made by animals digging for cicadas.

2) Look for cicadas under stones and slates. Some cicadas will burrow their way to the surface, but they hit a large stone or slate and can go no further. If you find them in this situation, gently put the stone or slate back. They will usually find their way around the obstruction once the time is right.

One clue that a Magicicada nymph is not ready to emerge is their eyes are still white. Their eyes turn red/orange prior to emerging (a few retain a white/blue color).

3) Cicada holes are about the size of a dime. Cicadas preemptively dig holes to the surface and wait until the weather is nice enough for them to emerge. Sometimes you can see them down in the holes.

4) Cicadas form chimneys above their holes when the soil is moist or muddy. These chimneys might look like a simple golf ball sized dome or a structure over six inches tall.

Periodical cicadas typically won’t emerge until their body temperature reaches approximately 65 degrees Fahrenheit (17-19.5 Celsius1). Their bodies are warmed by surrounding soil or warm water from rain. A good rule of thumb is, if the soil 8 inches(20 cm) deep is 65°, the conditions are good that they might emerge.

Our community (located in Ellicott City, Maryland) was built on former pasture land. When Brood X last emerged in 2004 none emerged from the ground in our area. But they sure did emerge in vast numbers in distant wooded areas. Many cicadas flew into our community and “colonized” all our new street trees and the MANY new trees that residents had planted on their property.

Now we are I finding lots (hundreds) of the small cicada chimneys (still closed on top) in our yard. They are little mounds or domes about 1-2 inches wide and high, made of wet mud. If you gently pick the mound off, there is a neat hole a little smaller than the size of a dime inside. I didn’t see the cicada, it must have gone back down until time to come out in a few weeks when the ground temperature reaches around 65 degrees. Then they’ll all emerge in their synchronized mass exit.

It’s going to be a doozy this cycle around here. I recommend going to the linked site which has lots of relevant pictures.

HAPPY BROOD X EMERGENCE to all of you in their range.

What magazines do they read?.................

Are you going to try any of the “seasonal” cicada recipes that emerge during these cycles? I hear the taste is interesting.

The Cicada Killer hornets are eagerly waiting...

Cicada killers prey on annual cicadas (as in your picture), mostly in late summer. Periodical cicadas emerge in early summer and are dead by July. I don’t know if cicada killers would know what to do surrounded by millions of orange-eyed, keening space-alien critters. A big periodical cicada emergence has to be seen (and heard) to be believed.

Cicada killers prey on annual cicadas which emerge in July and August. The 17 yr will be long gone by then.

We’re in a global disease pandemic, volcanos around the world are erupting, a plague of insects is coming, and Joe Biden is President. Just let that sink in.

Brood X has them outsmarted. Before the Killers emerge from their underground burrows, BROOD X cicadas have accomplished their generation’s breeding and, having fulfilled the mission, quickly die off. The Killers are left with the annual cicadas to harvest as the food supply for their underground offspring.
