The
Calpinae are a
subfamily of
moths in the
Erebidae family. 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 subfamily contains some large moths with wingspans longer than 5 cm (2 in).
