Striped pierrot tarucus nara
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.
Contents
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:
Afrotropical group:
South Asian group:
