Why was the specific epithet vestalis chosen for Bombus vestalis?

Answer

It references the Roman Vestal Virgins who tended sacred fires

The name is derived from the Vestal Virgins of ancient Rome, who were priestesses responsible for guarding a sacred fire. This naming convention is a subtle allusion to the way the female queen bee secretly invades and occupies the nest of a host species to carry out her own reproductive ritual.
