The Eastern Dappled White ''(Euchloe ausonia)'' is a southern Europe and Eurasian butterfly found mostly to the south and east of its almost indistinguishable relative the Western Dappled White. The wingspan is 40–48 mm. They go to an altitude of 1600 m. In most of its range, there are two generations. Adults are on wing from the beginning of March to the beginning of July. In mountainous and very dry areas, there is only one generation. The larvae feed on the flowers and young fruits of ''Sinapis arvensis'', ''Isatis tinctoria'', ''Isatis glauca'', ''Aethionema saxatile'', ''Iberis sempervirens'', ''Biscutella mollis'', ''Biscutella laevigata'', ''Bunias erucago'' and ''Aurinia saxatilis''. ==Systematics and subspecies== The three species ''Euchloe ausonia'', ''Euchloe crameri'' and ''Euchloe simplonia'' are closely related. Many authors refer to these species as the ''Euchloe ausonia''-complex, -superspecies or -species group.〔Dubatolov, V.V. and O.E. Kosterin (1994). "A new subspecies of the Euchloe ausonia Huebner species group from the highlands of the Dzungarian Alatau (East Kazakhstan) (Lepidoptera, Pieridae)." Atalanta (Marktleuthen) 25(3-4): 513-520〕 Sometimes ''Euchloe naina'' is also added to this group, but crossbreeding experiments suggest it may be a subspecies of ''Euchloe simplonia''.〔Back, W. (1990). "TAXONOMIC STUDIES WITHIN THE EUCHLOE-AUSONIA HUEBNER 1804 SPECIES GROUP (LEPIDOPTERA, PIERIDAE)." Atalanta (Marktleuthen) 21(3-4): 187-206.〕 Because of these taxonomic problems, the number of subspecies is not certain. The following subspecies are listed: *''Euchloe ausonia maxima'' Verity, 1925 (Crimea) *''Euchloe ausonia graeca'' (Verity, 1925) (Greece, southern Siberia) *''Euchloe ausonia pulverata'' (Christoph, 1884) (Tien Shan) *''Euchloe ausonia volgensis'' Krulikovsky, 1897 (southern Russia) *''Euchloe ausonia melisande'' Frühstorfer, 1908 (Jordan) *''Euchloe ausonia irinia'' Dubatolov & Kosterin, 1994 (Kazakhstan) 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「Euchloe ausonia」の詳細全文を読む スポンサード リンク
