Reports of emergences occurred from early Apr to early Jun with the majority of sightings occurring from mid-Apr to mid-May.
In 2011, periodical cicada emergences were reported in 19 South Carolina counties.
In South Carolina, the 1985 emergence began around 21 Apr in Abbeville and Saluda counties.
larvarum pupation lasted from 7 to 34 days and two emergence peaks were observed, accounting for respectively 40% (first peak) and 48% (second peak) of all emergences (Fig.
We identified the developmental stages associated with the different parasitoids, and the emergence pattern of adult parasitoids.

In keeping with the long history of cicada surveys in Ohio and Indiana, we surveyed both states for emergences and examined the effects of climate on triggering the start of an emergence.
Periodical cicada emergences were monitored with surveys of locations where the cicadas had been observed in 1987, 1991, 2001, and 2004.
Sixteen counties in southern Ohio experienced cicada emergences, with heavy emergences in parts of Hamilton, Clermont, Brown, eastern Butler, Warten, Clinton, Highland, Adams, Scioto, Lawrence, Gallia, Pike, Ross, and Greene counties (Fig.
As a result, they cannot settle the following problems: why are there emergences in nature?
This explains why there are so many novel and unexpected emergences.
However, the ecologic and evolutionary factors that constrain or facilitate such emergences are poorly understood.
The likelihood of disease emergence will depend on highly dynamic processes determined by both between- and within-species transmission rates.
We planned to look for meteorological factors that would predict when in May the emergence would begin, to map the extent of the brood in Indiana and Ohio, to re-examine the soil temperature as an environmental trigger to initiate the emergence, to assess the effects of clear cutting and replanting during the intervening years between emergences, to determine egg hatch rates, and to check the status of some of the offspring of the 2004 emergence at the end of 2004.
Newspaper reports published in the Cincinnati Enquirer provided information about the emergences in 1936, 1940, and 1953.
