Brood XIV Stragglers in Ohio, Part 3

Here’s another Brood XIV straggler from Roy Troutman’s yard. It’s hard to believe all that cicada once fit in that tiny skin.

Imagining Magicicada

In the coming days I’ll get a lot of emails from people telling me that they’ve found albino cicadas — well, they aren’t albinos, they just haven’t turned black yet. Once a cicada splits its nymph skin and imagines into the adult form, it takes some time for it to turn the familiar black color. Now, if you find a cicada with blue eyes, that’s different, that’s unusual (about 1 in 1000), so we want to hear about that.

This picture was take by Roy Troutman, last night in Batavia Ohio. It’s important to note that this is a Brood XIV straggler and not a Brood XIII cicada.

Brood XIV emerges before Brood XIII

Brood XIII cicadas are a bunch of slackers. Brood XIV stragglers (Brood XIV isn’t due until next year) have already emerged and imagined into their adult form around Ohio.

Here’s some photos from Matt Berger:

What’s up Brood XIII? What are you waiting for? An invitation?

Brood XIV Stragglers in Ohio

Illinois, Iowa, Indiana and Wisconsin aren’t the only states that can look forward to periodic cicadas.

Brood XIV stragglers are beginning to emerge in Ohio. So far we’ve had reports of chimneys from Roy and some photos of nymphs taken by Matt Berger in Terrace Park, Ohio (hopefully he’ll let us post the pics). Stragglers are periodic cicadas the emerge a year or more ahead or behind schedule. Brood XIV is due to emerge in many states next year (KY, GA, IN, MA, MD, NC, NJ, NY, OH, PA, TN, VA, WVA), but a few will emerge this year instead.

Here’s a photo of a cicada chimney taken by Roy Troutman in Ohio.

An interesting question about Neotibicen identification

Paul Krombholz has an interesting question about Neotibicen 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?

Variation in Neotibicen davisi

Paul Krombholz has discovered some interesting variations in the Tibicen davisi cicadas. I’m quoting Paul’s email in its entirety below.

Here is the composite photo showing variation in Tibicen davisi. The
additional one I wanted to add turned out not to be as dark as I thought,
but it has a different pattern. All these came from the trees in my
backyard in central Mississippi this season. Colors on the dorsal (top)
side vary from dark brown to green. Perhaps the most typical is the “olive”
one in the middle. On the ventral (bottom) side, the black abdominal stripe
varies from very wide to non-existent. Variation in the size of the black
abdominal stripe is not related to the color on the dorsal side, as I have
seen absolutely no abdominal stripe on both a greenish one and a very dark
brown one.

Davis described a variety of T. davisi—T davisi var. hardeni—which has
little or no abdominal stripe. However, it also has darkening next to the
wing veins of the seven marginal cells as in T. superbus
(http://static.flickr.com/31/60751246_f60d00e2a9.jpg?v=0), While its upper
side is “less rusty” than the typical T. davisi, its underside is also
green. (Dr. Alan Sanborn, personal communication). Since my examples only
vary as to the “greenness” of the upper side and to the size of the
abdominal stripe, none of them fit completely the description of var.
hardeni. If anyone finds a T. davisi that meets the description of var.
hardeni, I think Dr. Sanborn would like to know about it.
