Be on the lookout in 2022 (or any year)! Any place you see a red dot is a possibility. Even central Massachusettes (former home of Brood XI) and Ontario — maybe so.
What is a Magicicada:
A Magicicada is a genus of cicada that lives in the United States that typically emerges in 17 or 13-year cycles depending on the species.
They look like this:
What is a Brood:
A Brood is a numbered group of Magicicada cicadas that emerge in a specific series of years.
Example: Brood X (X is the Roman numeral for 10) emerges every 17 years, i.e. 2021, 2038, 2055, etc.
What is a Straggler:
A Straggler is a Magicicada that emerges earlier or later than anticipated.
Example: If a Brood XIX (13-year, next due in 2024) cicada emerges in 2022, we can say it is a straggler that emerged 2 years early.
Stragglers that emerge earlier than expected have also been called “precursors” (Marlatt 1898). I also call them “pioneers”.
Magicicada cicadas are often the victims of bird attacks or fungus infestation, which results in the removal of the cicada’s abdomen. Sometimes a bird removes the cicadas head. In both cases, the cicada’s body keeps moving, and some people question whether or not the cicada then becomes a zombie. No, the cicada does not become a zombie.
When Magicicada cicadas deposit eggs into a tree branch sometimes the branch dies, the leaves turn brown, and the branch droops like a flag. This is called flagging.
Here are some examples of flagging from the Brood X emergence in Princeton, NJ.
Typically flagging is more impactful to trees imported to North America, but it also impacts native species. The positive aspect is it prunes weaker branches, which helps the tree, and helps other plants in the shade of the tree.
