''Tarucus'' is a butterfly genus in the family Lycaenidae. They are commonly known as blue pierrots or simply "pierrots". But the latter name is often used for the very closely related genus ''Castalius''. In fact, the delimitation of ''Castalius'' versus ''Tarucus'' is not yet fully resolved, with some species, such as the Dark Pierrot (''T. ananda''), having been moved between the two genera repeatedly. It may even be that they are eventually regarded as synonymous, and in that case the older name ''Castalius'' would supersede ''Tarucus''. Several species formerly in ''Tarucus'' have recently been moved to ''Leptotes'', another closely related lineage (though not quite as close as ''Castalius''). The caterpillars of this genus typically feed on ''Zizyphus'' and are attended by ants. ==Species== The genus can be divided in two distinct groups. These are generally separated geographically, but some taxa (such as the Black-spotted Pierrot, ''T. balkanicus nigra''), though assigned to one group, occur in the range of the other. Consequently, it is not quite clear whether the groups are clades or merely convenient but paraphyletic assemblages:〔Brower (2008), and see references in Savela (2009)〕 Afrotropical group: * ''Tarucus balkanicus'' – Balkan Pierrot, Little Tiger Blue * * ''Tarucus balkanicus nigra'' – Black-spotted Pierrot * ''Tarucus bowkeri'' (Trimen, 1883) * ''Tarucus grammicus'' (Grose-Smith & Kirby, 1893) – Black Pierrot * ''Tarucus kiki'' Larsen, 1976 * ''Tarucus kulala'' Evans, 1955 – Turkana Pierrot * ''Tarucus legrasi'' Stempffer, 1944 – Le Gras' Pierrot * ''Tarucus quadratus'' Ogilvie-Grant, 1899 * ''Tarucus rosacea'' (Austaut, 1885) – Mediterranean Tiger Blue, Mediterranean Pierrot * ''Tarucus sybaris'' (Hopffer, 1855) * ''Tarucus theophrastus'' – Pointed Pierrot, African Pierrot, Common Tiger Blue * ''Tarucus thespis'' (Linnaeus, 1764) * ''Tarucus ungemachi'' Stempffer, 1944 – Ungemach's Pierrot South Asian group: * ''Tarucus alteratus'' – Rusty Pierrot * ''Tarucus ananda'' – Dark Pierrot * ''Tarucus callinara'' – Spotted Pierrot * ''Tarucus extricatus'' – Rounded Pierrot * ''Tarucus indica'' * ''Tarucus nara'' – Striped Pierrot * ''Tarucus venosus'' – Veined Pierrot, Himalayan Pierrot * ''Tarucus waterstradti'' Druce, 1895 * * ''Tarucus waterstradti dharta'' – Assam Pierrot 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「Tarucus」の詳細全文を読む スポンサード リンク
