New paper about Brood XXII Magicicadas

There is a new paper out about Brood XXII, titled Evolution and Geographic Extent of a Surprising Northern Disjunct Population of 13-Year Cicada Brood XXII (Hemiptera: Cicadidae, Magicicada). I helped with the field work for this paper, traveling through Ohio and Kentucky with Roy Troutman, recording the locations of periodical cicadas.

Brood XXII, a brood of Magicicada periodical cicadas with a 13-year lifecycle, exists in Louisiana & Mississippi, and Ohio & Kentucky with no geographic connection between them (the two groups are geographically isolated). The paper discusses the similarities and differences between the two groups.

You can read and download the paper for free.

Did Someone Offer a Reward for White or Blue-eyed Cicadas?

Filed under: Eye Color,FAQs,Magicicada,Roy Troutman — Dan @ 7:58 am

Is it true that someone has offered a reward for a white or blue-eyed Magicicada cicadas?

This was false and an urban legend until in 2008 when Roy Troutman began to offer rewards for living blue-eyed cicadas for scientific research. All cicadas were released, unharmed.

Important: Roy is no longer offering the reward as he has obtained the cicadas needed for his research. So, don’t bug him, unless you want to tell him that his photos and video are awesome.

White or Blue-eyed Magicicadas cicadas are extremely rare, so finding them can be difficult. I usually find one per emergence, and that is after looking at thousands of cicadas.

Speaking of Roy and White-eyed cicadas, here is a video Roy took of a White-eyed cicada:

And here’s a white and orange-eyed cicada taken by Roy:

From Roy Troutman: “I shot a video back in 1991 of a 17 year Magicicada cassini singing right on my hand.”

The excavation skills of cicadas

Filed under: Cicada Anatomy,Magicicada,Roy Troutman — Dan @ 8:01 am

Cicadas spend most of their lives, as nymphs, underground. The large forelegs of cicada nymphs are adapted to digging through soil.
