Walking tour of streets in Seoul!
Today’s video is a first-person perspective walk tour of Cheongdam Park, Seoul, South Korea. Although highly developed, Cheongdam Park remains as a soothing natural oasis that is relatively untouched by city pollution. The park is quite crowded in the morning with people who exercise and offers a resting place to enjoy the fresh air thanks to many trees in the park. In the Summer, Cheongdam Park gets filled with the sound of cicadas. As soon as the temperature rises above 28 °C, the air begins to vibrate with their song, one of the loudest any insect can produce. Some cicada songs can reach up to 120 dB, as loud as a power saw or a motorcycle. I personally love the sound of cicadas; for me it's the sound of summer. I hope you enjoy the walk as much as I did :)

The cicadas (/sɪˈkɑːdə/ or /sɪˈkeɪdə/) are a superfamily, the Cicadoidea, of insects in the order Hemiptera (true bugs). They are in the suborder Auchenorrhyncha,[a] along with smaller jumping bugs such as leafhoppers and froghoppers. The superfamily is divided into two families, Tettigarctidae, with two species in Australia, and Cicadidae, with more than 3,000 species described from around the world; many species remain undescribed.
Cicadas have prominent eyes set wide apart, short antennae, and membranous front wings. They have an exceptionally loud song, produced in most species by the rapid buckling and unbuckling of drumlike tymbals. The earliest known fossil Cicadomorpha appeared in the Upper Permian period; extant species occur all around the world in temperate to tropical climates. They typically live in trees, feeding on watery sap from xylem tissue and laying their eggs in a slit in the bark. Most cicadas are cryptic. The vast majority of species are active during the day as adults, with some calling at dawn or dusk. Only a rare few species are known to be nocturnal.
One genus, the periodical cicadas spend most of their lives as underground nymphs, emerging only after 13 or 17 years. The unusual duration and timing of their emergence may reduce the number of cicadas lost to predation, both by making them a less reliably available prey (so that any predator who evolved to depend on cicadas for sustenance might starve waiting for their emergence), and by emerging in such huge numbers that they will satiate any remaining predators before losing enough of their number to threaten their survival as a species.
The annual cicadas are species that emerge every year. Though these cicadas have lifecycles that can vary from one to nine or more years as underground larvae, their emergence above ground as adults is not synchronized, so some members of each species appear every year.[1]
Cicadas have been featured in literature since the time of Homer's Iliad, and as motifs in art from the Chinese Shang dynasty. They have also been used in myth and folklore as symbols of carefree living and immortality. The cicada is also mentioned in Hesiod's Shield (ll.393–394), its voice sings when millet first ripens. Cicadas are eaten by human beings in various countries, including China, where the nymphs are served deep-fried in Shandong cuisine.
