The genus ''Neotibicen'' comprises large-bodied Cicadidae appearing in late summer or autumn in North America.〔(【引用サイトリンク】url=http://insects.ummz.lsa.umich.edu/fauna/Michigan_Cicadas/Michigan/Index.html )〕 Many colloquial names exist for ''Neotibicen'', including locust, and dog-day cicada. Up until recently, these species were all in the genus ''Tibicen'', which has now been redefined so as to include only a few European species, while species from the Western US and Mexico are now placed in a separate genus, ''Hadoa''.〔http://www.mapress.com/zootaxa/2015/f/zt03985p251.pdf〕 ''Neotibicen'' species are the most common cicada in the Eastern United States. Unlike periodical cicadas, whose swarms occur at 13- or 17-year intervals, ''Neotibicen'' species can be seen every year, hence their nickname "annual cicadas". The life-cycle of an individual, however, is more than a year. Nymphs spend two or three years feeding on tree roots before they emerge. Their annual reappearance is due to overlapping generations. ''Neotibicen'' cicadas are long, with characteristic green, brown, and black markings on the top of the thorax, and tented, membranous wings extending past the abdomen. The fore pair are about twice the length of the hind pair. Adults feed using their beak to tap into the xylem of plants; nymphs feed from the xylem of roots. ==Communication== Like other members of the subfamily Cicadinae, ''Neotibicen'' species have loud, complex songs, even (in many cases) distinct song phrases.〔(【引用サイトリンク】url=http://www.insectsingers.com/100th_meridian_cicadas/index.html )〕 Males produce loud calls in the afternoon or evening (depending on the species) to attract females. These sounds, distinctive for each species, are produced by organs below the abdomen's base. These calls range from a loud buzz to a long rattling sound. 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「Neotibicen」の詳細全文を読む スポンサード リンク
