Besseria atra
Besseria atra is a species of tachinid fly in the subfamily Phasiinae. It was originally described as Apinops atra by Coquillett in 1897 before being transferred to the genus Besseria. The species is known from North America and belongs to a group of parasitoid flies whose larvae develop inside other insects.
Siphosturmia
Siphosturmia is a genus of tachinid flies established by Coquillett in 1897. The genus comprises eleven described species distributed across the Americas. At least one species, S. rafaeli, has been documented as a parasitoid of lepidopteran larvae, specifically Diatraea saccharalis. Like other tachinids, members of this genus are presumed to be parasitoids of arthropods, though species-level biological data remain sparse.
