Pycna semiclara, known as the Whining Forest Cicada, is a South African forest-dwelling platypleurine cicada. One of the largest cicadas in South Africa, this species reaches 40–50 mm in length. Its wings display green, brown and translucent patches, and are covered with silvery hairs. It is endemic to South Africa, and occurs in the Eastern Cape, KwaZulu-Natal, Mpumalanga and Limpopo provinces. It prefers indigenous forests, where undergrowth is sparse and trees are more than 4m tall, but may also be found in stands of Quercus robur, Populus deltoides, pine and eucalyptus.
