Name: 털매미, Turmaemi
Scientific name: Platypleura kaempferi (Fabricius)
Distribution: Korea, Japan, Taiwan, Kuril Island, Malaysia and Borneo Island

This cicada is about 20 to 25 millimeters long and its wing span is around 35 to 40 millimeters. It is black brown in color with white power scattered across its entire body. The mesonotum, a part of the exoskeletal plates in the thorax, is glossy black with W-shaped patterns in green or reddish brown. The forewings are glossy, too, with cloud-like patterns in black brown and reddish brown. Normally, the connecting parts between the body and wings develop patterns in gray-yellow, similar to the barks of trees, and function as a camouflage.

Ecology: This cicada is widely observed in and around cities, towns and mountains. The adults are most active during August. The nymphs tend to inflict injuries to the roots of broadleaved trees such as willows and poplars. Sometimes, adults spawn on apples, causing damage to farmers.

This mushroom grows in clusters from the stumps of fallen and dead broadleaf trees. It resembles the oyster mushroom, but consists of smaller spores, thinner tissues and differentiates itself from other species by the changing colors of its cap. The cap is white or light grayish brown at first and then turns to white or light yellow. It is about 1 to 3 millimeters thick in the center and smells like flour. The pleats are densely arranged. It is white at first and turns cream and yellowish green with the passage of time.
