The 2017 Cicada Mystery

Periodic Cicadas

Periodic Cicadas

This year periodic cicadas are emerging across Maryland and Washington, DC. The last large emergence in Maryland was Brood X in 2004. Brood X is expected to emerge in 2021. Brood VI emerged in NC, TN and GA earlier this year. Brood VI in the past has had heavy emergence in IL, MI and WI. The question cicada sleuths are asking: “Is the current emergence in MD Brood part of Brood X that is emerging 4 years early? Or could the emergence be part of Brood VI. If it is Brood VI, are there factors that cause it to increase its range or cause populations to fluctuate over time? If it is Brood X, what is causing large numbers to emerge early. Many studies and tests will be needed to arrive at a conclusion.
