Final yr, Kentucky obtained to expertise the group of periodical cicadas often known as Brood X bursting onto the scene, singing their tune, mating in bushes, and dying in spectacular numbers.
It’s like nature’s most morbid Mardi Gras.
There have been seemingly billions of cicadas right here in Kentucky and since folks had been keen to report sightings to numerous avenues, we had been capable of map and higher perceive the place these bugs dwell in Kentucky.
Whereas the cicadas that had been born final yr gained’t see the sunshine of day till 2038 and the following large brood in Kentucky (Brood XIV) gained’t emerge till 2025, you continue to would possibly spot a few of these long-lived critters proper now.
Periodical Cicada Fundamentals
Periodical cicadas are totally different from the cicadas you see yearly, aka the annual cicadas. Because the identify implies, they solely emerge periodically, both each 13 or 17 years. There are seven totally different species of periodicals: 4 13-year species and three 17-year species.

Straggler Phenomenon
Not all periodical cicadas within the U.S. come out at the very same time. Their appearances are staggered with years the place pockets of them will emerge. We name these “Broods.” There are presently 15 broods which were noticed in Kentucky.
Straggler cicadas are cicadas that emerge in off years from these anticipated emergences.
To oversimplify issues, these cicadas appear to have “misplaced rely” and are popping out at an odd time. Many stragglers are a yr late, although there are additionally stragglers that may be years early or late, and presumably errors of three years as nicely. In Kentucky, we might be seeing Brood X cicadas which might be off by 1 yr or we might be seeing Brood XIV cicadas displaying up threee years early.
How might a cicada lose rely?
As nymphs within the soil, cicadas feed on the sap of the tree. They’ll log the variations between seasons when sap is plentiful and when it’s at a low level, which helps them to tabulate the years they’ve been belowground. Plus, we’ve all been there, proper? You swear you gained’t lose rely of one thing necessary and positive sufficient you might be again to counting it!
Will There Be Any Points?
Stragglers aren’t simply known as that as a result of they endure punctuality points. Additionally they have a tendency to return out in smaller numbers than the official brood years.
A lot of them can be rapidly devoured up by hungry snakes, birds, and different critters. There shouldn’t be the problems we noticed final yr with elevated ranges of noise or injury accomplished to younger bushes.
