![]() ![]() Woodcut portrait of Benjamin Banneker for the title page of a Baltimore edition of his 1795 Pennsylvania, Delaware, Maryland, and Virginia Almanac.Īnother intellectual who wrote at length about the periodic cicada was Benjamin Banneker (1731-1806), a black scientist, astronomer, almanac author, and general polymath from Maryland, who witnessed the same cycle of Brood X in 1749, and accurately predicted their return in 1800. It also includes many aspects that will be central to later cicada accounts, including a nighttime emergence, their loudness, shells, the fact that they are harmless, a connection to the Bible, and thoughts of eating them (and connecting eating them to indigenous Americans, which is most certainly what Sandel meant when he wrote “heathens”). Though himself not a scientist, Sandel’s account is a compelling look at Brood X. The insects lived until June and then they died.” This may be the same type of insect as that which John the Baptist is said to have eaten. The newly emerged insect is fried a little and then eaten. The heathens eat them, especially just after they emerge. In spite of this the trees did not show any injury the following year. The insects slit the bark of the branches and trees and deposited the worms. Since they were so numerous throughout the country, cowbells could scarcely be heard in the woods because of the noise. There they made an extraordinary sound from morning ’til night. After coming out of the ground they emerged from their shells, and flew away settling in the trees. It seems strange that they could make a hole through the ground while covered with a shell. A shell completely covered the mouth, body and feet. ![]() They appeared everywhere even on hard roads. “During the month of May, there came out of the ground a particular fly or grasshopper which the English call locusts. In his account of the 1749 cicadas, he recounted the writings of the Andreas Sandel, Pastor of the Gloria Dei Swedish Lutheran Church in Philadelphia, who noted in his journal in 1732: Pennsylvania had long been an epicenter of cicada activity, which is something that Kalm knew all too well. ![]() Though, importantly, cicada are not locusts at all: they are from who different families of insects. Kalm’s 1749 account describing the appearance of cicadas in Philadelphia was the first published scientific account of the cicada as we know it, Magicicada septendecim, the 17-year locust. This Log Blog will show some historical accounts of the periodic cicada to try to shed light on this strange, every 17 year, phenomenon. The swarm that Kalm witnessed was the cicada special event we now call, somewhat ominously, Brood X. The insects, which Kalm described as grasshoppers, were what we now know as the periodical cicada. Or it could be someone else entirely.ġ749 was a locust year, and Pehr Kalm, the Finnish explorer, botanist, naturalist, and student of Carl Linneaus, 1 was in Pennsylvania to witness it. Some think the portrait might be of Peter Adrian Gadd (1727–1797), also of the Royal Academy. The person is commonly assumed to be Peter Kalm (1716–1779). Mystery man: Portrait of an unnamed Royal Academy of Turku professor, probably by Johann Georg Geitel, 1764. It is highly unlikely that dung beetles account for all the holes utilized by these insects.” Peter Kalm, 1749 They burrow the ground, no matter how hard wherever the excrement of horses is found. I do not know if they dig the holes themselves in which the nymphs lie, or if they avail themselves of those dug by various types of earth boring dung beetles. This may be the reason why the Creator has foreordained that they should appear at night, so they may not be destroyed by birds before they have reached the stage where they can fly away. They are especially appetizing to birds at this stage. Chickens are greedy about the insects just as they creep out of their holes. Newly emerged insects dry their wings before attempting flight. The ground underneath the trees is often covered with discarded pupal cases. The nymphal cases, which split on top as the insects emerge, are discarded, but remain attached to trees and plants until, blown to the ground or washed away by rain. “They usually come out of their holes at night and climb trees and the stems of plants.
