The Calpinae are a subfamily of moths in the family Erebidae described by Jean Baptiste Boisduval in 1840.
This subfamily includes many species of moths that have a pointed and barbed proboscis adapted to piercing the skins of fruit to feed on juice, and in the case of the several Calyptra species of vampire moths, to piercing the skins of mammals to feed on blood.
The Calpinae are most closely related to a clade including the subfamilies Eulepidotinae and Hypocalinae, which are also among the Erebidae.
The tribes Anomini and Scoliopterygini, previously included in the Calpinae, were found to be distantly related and were reclassified into a separate subfamily as the Scoliopteryginae.
The phylogenetic structure of this group was essentially unresolved, and in many cases it was even doubtful whether the genera were indeed correctly placed in this subfamily.
