"Singing was evident, and some of the specimens had smaller red bands on the ventral surface of the abdomen, and could possibly  be M. septendecula.  Numbers were not as great as those in gamelands 246 in Dauphin County, but adults were easy to find."

"I reported the beginning of emergence on May 16 at Fair Hill, MD. Only one group, at the extreme south end of the park was singing that day, but emergence had begun, presumable the night before, at localities throughout the park (I cover 20 miles of trail on my weekly mountain bike ride there). In any case, the ones singing were septendecim, the only species I had heard previously. Today (May 22) I did the same ride and they were singing at many localities. However, at one, north of Black Bridge Rd east of Elk Creek, I heard M. cassini in addition to septendecim. So far everything I have collected appear to be septendecim (the overwhelming majority, ID'd by ear). But I recorded cassini songs and they match the song posted on the Michigan site. This is the only site I heard cassini. There is no way you could confuse them with septendecim. I encourage everyone to listen to the recordings on the Michigan web site to familiarize themselves with the various species. The songs are radically different from each other."

"I went back to Fair Hill, MD this morning and can now report that all three species of cicadas are present. M. septendecim is the most abundant by a large margin, but at several spots in the park I heard cassini, too, and at one spot I heard all three: septendecim, cassini and septendecula. The septendecula were high up, so I couldn't collect any. This spot is about 200m due east of the Gallaher Rd. parking area (#4). From that lot, proceed east, across Gallaher Rd. Follow the dirt road down through an old hedgerow for 1-200m. All three species could be heard in this area."
"At one spot at the edge of an orchard at the southern-most point in the park (known to mountain bikers as "South Park") I collected both septendecim and cassini. (This is the only spot in the park I heard singing last weekend, May 16.) M. cassini is smaller, and has less extensive reddish coloration. In particular, there is no reddish banding on the abdominal sterna. I made close up recordings of individuals of both cassini and septendecim at the orchard. It is much easier to get close to singers in the orchard as the apple trees are only about 7 feet tall. My recordings of all three species match those posted on U of Michigan's web site: http://insects.ummz.lsa.umich.edu/

Cicadas were observed on Sunday May 23, 2004 during the middle of the afternoon.  "They were singing quite loudly. I am not an entomologist by training, but I would say that they were very abundant.  There were some trees that had multiple cicada casings (exuviae) per leaf.  We also observed many adults climbing the trees and flying around."

"At the last AES meeting on April 28, Charles Bartlett noted that Magicicada cassini had not been recorded from Delaware. This morning (May 24, 2004) I collected a M. cassini perched on the front door of Brown Laboratory at the University of Delaware. It is considerably smaller than the other species and is entirely black on the underside of its abdomen.
     Another observation/curiosity. If you cup your hands loosely over your ears, the chorus sound of Magicicada is amplified significantly. This phenomenon works even if your hands are flat and about a inch away from the sides of your head. I presume the frequency of the cicada calls are selected preferentially at that distance somewhat like hearing "the sea" by holding a conch shell to one's ear."

Abundant cicadas of all three species. Chorusing loudest at bottom of parking lot. Exuvia abundant, one teneral adult, mating, egg laying, specimens taken of all three species for collection of The Academy of Natural Sciences; also a sound recording made. Cicadas also at the Welcome Center opposite on southbound I-95, but the northbound site is much better.

"I ran into cicadas (literally) yesterday, 8 June, while driving north on Interstate 81.  There were none in the Raphine area (Virginia mile 205) and people were looking for them.  Rumor had that they were as far south in the Valley as Harrisonburg.  I encountered them in great numbers around Winchester. I stopped for lunch at a Taco Bell at Virginia mile 317, roughly longitude  78°00', latitude 39°11' [see more precise lat./long. estimate above based on location of Taco Bell west of I-81 nr. VA mile 317], and found the area swarming with cicadas, apparently nearly all M. cassini.  The males were evidently giving their courting call in unison; it sounded like someone was operating an electric drill.  It was 12:45 PM EST on a warm, humid day (probably over 25° C) with bit of haze following a spell of cooler weather.  I saw no exuviae but the area had probably been built over since 1987, so that would not be surprising.  I did not notice signs of oviposition.  There were dozens in a small peach or cherry tree by the parking lot, a few flying, and a good many calling.  There were also hundreds lying dead or quiescent on the ground.  I collected a few in a plastic container and sorted them out later:  of 22 specimens, I apparently had 15 male cassini, 6 female cassini, and one lone male septendecem.  I'll keep the container in the freezer for a while in case anyone has further questions.  I looked for cicadas when I got to Pennsylvania (47 miles further north) but saw none."
