Tibicen canicularis – Dog Star Rising

Filed under: Annual,Tibicen — Tags: , — Dan @ 9:34 am

Mid-August is approaching, and the “Dog Days” of summer are almost here. Sirius (the Dog Star) and the constellation Canis Major will soon begin to appear in the early morning sky. Now is also the time that Tibicen canicularis, the Dog Day Day cicada, is also making its presence known in the U.S.A.

This is a photo of a T. canicularis (Dog Day cicada) next to a T. davisi (Southern Dog Day cicada) by by Paul Krombholz:

T. canicularis looks quite different from T. davisi

T. canicularis has a green pronotal collar, green markings on its pronotum, and at least some, if not all, orange colors on its mesonotum (where the M is on the cicada’s back). T. canicularis sounds like (to me at least) a circular saw buzzing through a plank in wood in a neighbor’s garage.

Imagine that you are a farmer waking just before dawn and seeing the first signs of Sirius, the Dog Star, and then later in the day, hearing T. canicularis singing away in the trees surrounding your fields. Those two signs are signals that summer is reaching its peak, and harvest will start soon enough.

T. canicularis can be found in the following states and provinces: AR, CT, DC, IL, IN, IA, KS, ME, MB, MD, MA, MI, MN, MO, NE, NB, NH, NJ, NY, NC, ND, NS, OH, ON, PA, PE, QC, RI, SC, SD, TN, VT, VA, WV, WI.

Here is a screen capture of the computer app Stellarium, with Canis Major and Sirius rising above the horizon before dawn.

Michigan Tibicens

Filed under: Tibicen — Tags: — Dan @ 7:24 pm

Patrick Farr sent us this cool picture of two adult cicadas climbing on his hand. They’re Tibicens, but I’m not sure of the species.

Gerry Bunker said in the comments that this is likely a T. canicularis.

An interesting question about Tibicen idenitfication

Filed under: Paul Krombholz,Tibicen — Tags: , — Dan @ 2:52 pm

Paul Krombholz has an interesting question about Tibicen identification.

In Kathy Hill’s picture of 18 species, T. canicularis looks quite different from T. davisi, but I have at least one T. davisi, captured in my back yard, that looks very similar to three canicularis individuals I caught in Northern Illinois a couple of weeks ago. The canicularis individuals all have the white “hip” spots and none of my davisi have them have them. T. davisi has a slightly larger head. The big question is, What features reliably distinguish the two species considering all the variety seen within species?
