What unique liquid do moths in the genus Calyptra consume?

Explanation:
Calyptra moths demonstrate hematophagy, meaning they feed on blood rather than the usual nectar. Some species in this genus have evolved to take small amounts of mammalian blood at night, using their proboscis to sample the liquid from hosts. This makes blood the unique liquid they consume compared with most moths, which typically rely on nectar. Water and sap are not distinctive feeding liquids for these moths, and nectar is the more common option for most adult Lepidoptera.
