Anthrax aterrimus
Anthrax aterrimus is a bee fly in the family Bombyliidae, subfamily Anthracinae. The larval stage has been documented as an external parasite on the pre-pupal or pupal stages of the mason wasp Monobia quadridens. As with other members of the genus Anthrax, adults likely visit flowers for nectar. The species was described by Bigot in 1892.
