Brood X 2021 Princeton, New Jersey
The Princeton Battlefield (historical location of one of George Washington’s battles) has always been a great place to find Brood X periodical cicadas.
Here are a few photos I took last weekend:

What are the black spots on the back of a Magicicada cicada?
The question I saw most this year (2021) was “what are the black spots on the back of cicadas for”? The people asking this question are specifically talking about Magicicada cicadas that have recently molted and are still white/cream colored and soft (teneral from the Latin word “tenen” meaning soft).
The area of the cicada where the black spots appear is called the pronotum — “pro”, meaning before in Greek, and “notum”, meaning the back, also in Greek. Before the back.
The spots contain a pigment that will gradually spread throughout a cicada body as it hardens, and transforms from white to black.
People speculate that the two black spots resemble eyes, and that might scare away predators. This might be possible, but I haven’t read anything to substantiate the hypothesis.

Periodical cicada nymphs emerging at night
One of the most fun periodical cicada experiences is watching thousands of nymphs emerge from the ground at night, and crawl to the nearest vertical surface (hopefully a tree) and begin to molt.
This is a video by Roy Troutman from 2007 of the Brood XIII emergence, specifically in Ryerson Woods in Illinois:

Here’s a time-lapse video, also by Roy, of a cicada nymph molting:

Megatibicen dorsatus is arguably the most beautiful cicada in the United States. Even it its teneral (meaning soft) form right after molting, in is visually impressive.
These three photos were taken by Greg Holmes of a Megatibicen dorsatus in its post-molting, teneral state.
