Sand Fairy Sylphoides arenaria (Distant, 1907)
© Popple Creative Industries 2014–2023
Previously known as Cicadetta arenaria. Species number (TNS): 250. Fore wing length: 16–17 mm. Distribution and seasonality: Restricted to less developed beaches of the New South Wales coast. Historical records indicate that it was present from Ballina south to Bermagui (Moulds, 1990); however the species appears to have disappeared from Ballina and is likely to occur only from south of Evans Head. It was once widespread in the Greater Sydney region, but appears to have gone extinct in that area due to removal of habitat. Adults can be present from December to February. Notable localities: Gerringong, Jervis Bay. Habitat: Relatively undisturbed beaches with a well-developed area of dunes covered in Hairy Spinifex (Spinifex sericeus). Calling song and behaviour: A rather musical series of double- note clicks. Singing occurs in bright sunshine. Adult cicadas (and presumably nymphs) occur perhaps exclusively on Hairy spinifex. Protection of the host plant would be a wise initiative in allowing preservation of this unique cicada. At some locations it is a common species, but it is often uncommon in marginal habitats and disturbed areas. Similar species: None, although Wallum Sedge- clicker shares some broad similarities. Beach Squeaker can be encountered in the same habitat. database record
