Moreover, the first time the Society had heard about periodical cicadas was from Paul Dudley, who sent a manuscript to the Society in 1733. .... Dudley correctly noted the seventeen-year life cycle and provided evidence. However, Collinson's paper shows that he used Bartram's claim of a fifteen-year cycle in his paper.
Typically cicadas with a 17-year life cycle will emerge 4 years early, and cicadas with a 13-year cycle will emerge 4 years late.
Both Brood XIX and XIII exist in Macon, Sangamon, Livingston and Logan counties in Illinois. The easily accessible place they come closest to overlapping is Springfield, Illinois, which is in Sangamon County.
During the period of infestation, Indian women and children collect the insects in baskets and carry them home. They are then fried and eaten as a delicacy.Republished by "Knowledge Bank".

The northern Illinois brood, which will emerge in late May 2024, has a reputation for the largest emergence of cicadas known anywhere. This is due to the size of the emergence and the research and subsequent reporting over the years by entomologists Monte Lloyd and Henry Dybas at the Field Museum in Chicago. During the 1956 emergence, they counted an average of 311 nymphal emergence holes per square yard of ground in a forested floodplain near Chicago. This translates to 1½ million cicadas per acre. In upland sites, they recorded 27 emergence holes per square yard, translating to about 133,000 per acre. This number is more typical of emergence numbers but is still a tremendous number of insects. .... 2020 | Northern Illinois Sub-Brood (part of Marlatt's XIII)

Brood XIX and Brood XIII will both emerge this spring. The last time these bugs showed up at the same time in the United States, Thomas Jefferson was president. After this spring, it'll be another 221 years before the broods, which are geographically adjacent, appear together again.

Folks in Northeastern Ohio complain of itchy welts on their heads, neck and upper torso. The oak itch mite, Pyemotes herfsi, has been identified as the culprit. The last time Ohio suffered an outbreak was in 2008 in the Cincinnati area. At that time, walkers, joggers and cyclists were complaining that when they followed trails that were overhung by oak trees, they would end up with itchy welts the following day. At that time, the oak itch mite had been recorded as being a periodic pest from Nebraska to Texas and eastward to Tennessee. The bites were most common in July and August, but the following summer, there were no complaints!
The egg laying activity of female cicadas may also affect mast crops (nuts, acorns) which reduces food for squirrels. It is noted that Eastern gray squirrel populations often decline after a cicada cycle.
Brood XIX is arguably the largest (by geographic extent) of all periodical cicada broods, with records along the east coast from Maryland to Georgia and in the Midwest from Iowa to Oklahoma.
To date, we have surveyed and mapped over 10,000 localities within periodical cicada emergences, using detailed base maps and GPS technology, such as the custom GPS datalogger ... .
