''Cicadetta montana'' (also New Forest Cicada) is a species of Cicadetta found throughout Europe and in parts of Asia.〔 "Cicadetta montana Scopoli, 1772 Distribution: AT, BE, BG, DK, FI, FR, DE, GB, GR, HU, IT, NO, IL, PL, ES, SE, SLO, TR, AZ, GG, KG, MD, N-RU, M-RU, S-RU, TJ, UA, YU." (''The Fulgoromorpha and Cicadomorpha of Turkey'' - Emine Demir )〕 It is regarded as endangered over large parts of Europe, and has vanished from several areas in Western Europe. 〔''An Encyclopedia of Natural History''〕 It is the only cicada species native to England and Finland (Åminneforss in Pohja).〔The genus is also represented in Australia and New Zealand. (''Cicada sensations, behavior, song patterns'' )〕 The adult females inject their eggs into the stems of food plants and when the larvae emerge, they burrow underground and as nymphs feed on root sap. These underground cycles may last many years, differing for each species. Females have a body measuring about 50mm in length, the males being much smaller. It has transparent wings with prominent veins, folded over the back when at rest, and a dark slate-grey or black body with dull orange rings around the abdomen. The legs are marked with dull orange as are the leading edges of the wings (costae). As with all cicadas, the males produce the shrill, buzzing calls by rapidly flexing drumhead-like membranes, while the females are limited to producing clicks. The call of ''C. montana'' sounds like static hiss to the unaided human ear.〔(Sound clip from ''Songs of Cicadas'' )〕 The call of ''C. montana'' is sustained with relatively short lulls at irregular intervals. Their shrilling was venerated by the ancient Greeks, but detested by Virgil.〔(''Taxonomy, distribution, biology and conservation status of Finnish Auchenorrhyncha'' - Guy Söderman )〕 ==Food plants== *''Betula pendula'' (European white birch) 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「Cicadetta montana」の詳細全文を読む スポンサード リンク
