Catapaecilma major, the common tinsel,[2][3][4] is a species of butterfly belonging to the lycaenid family described by Hamilton Herbert Druce in 1895.

It is found in the Indomalayan realm.

[5][4][2][3][6] The two Bornean specimens (females) [of Catapaecilma elegans] before me differ from Sikkim examples by the central band on the fore wing below being straight, not Y-shaped, as appears to be invariably the case in Indian specimens, also in those from Ceylon, and again from Sumatra.

On such slight material I do not propose to admit at present that the Indian representatives belong to a distinct species (they are certainly not typical), but in the event of their requiring a name I would suggest major.The larvae feed on Terminalia paniculata.

The subspecies are:[2][3][4]
