Ablautus arnaudi
Ablautus arnaudi is a small species of robber fly in the family Asilidae, first described by Wilcox in 1966. Adults measure approximately 6–7 millimeters in length. The species exhibits sand-colored cryptic coloration and displays distinctive sexual dimorphism in facial hair coloration. Males possess bright white facial hairs and engage in elaborate courtship displays involving leg-waving and rocking movements. Like all Asilidae, this species is predatory in both adult and larval stages.

Efferia antiochi is a species of robber fly (family Asilidae) described by Wilcox in 1966. The genus Efferia comprises large, predatory flies in the subfamily Asilinae, characterized by their robust build, prominent compound eyes, and strong predatory behavior. Efferia antiochi is one of numerous species in this diverse genus, which is primarily distributed in arid and semi-arid regions of North America. Like other robber flies, adults are aerial predators that capture other insects in flight.
Efferia azteci
Efferia azteci is a species of robber fly in the family Asilidae, described by Wilcox in 1966. The genus Efferia belongs to a group of large, predatory flies commonly known as robber flies, which are characterized by their stout bodies, prominent compound eyes, and predatory behavior. This species is part of a diverse assemblage of Asilidae found in North America, with members of the genus often exhibiting distinctive sexual dimorphism in abdominal coloration patterns.
Efferia duncani
Efferia duncani is a species of robber fly in the family Asilidae, first described by Wilcox in 1966. The genus Efferia comprises large, predatory flies that are morphologically similar to the related genus Triorla. Robber flies in this group are characterized by their robust build, large eyes, and predatory behavior. Specific ecological details for E. duncani remain poorly documented in the available literature.
Efferia neoinflata
Efferia neoinflata is a species of robber fly (family Asilidae) described by Wilcox in 1966. It belongs to a diverse genus of predatory flies distributed primarily in the Americas. The species epithet "neoinflata" suggests a relationship to or distinction from E. inflata, a pattern common in Efferia species nomenclature. As with other robber flies, adults are aerial predators that capture other insects in flight. The genus Efferia was historically treated as a subgenus within a broader concept of Asilus but has been elevated to full generic status in modern classifications.
Efferia pinali
Efferia pinali is a species of robber fly (family Asilidae) described by Wilcox in 1966. As a member of the genus Efferia, it belongs to a diverse group of predatory flies found primarily in the Americas. The specific epithet "pinali" suggests an association with pine habitats or the Pinal region, though explicit habitat documentation for this particular species is limited. Robber flies in this genus are generally medium to large-sized predators that hunt other insects in flight.
Haplopogon utahensis
Haplopogon utahensis is a species of robber fly (family Asilidae) described by Wilcox in 1966. As a member of the diverse Asilidae family, it is a predatory dipteran. The specific epithet 'utahensis' indicates a connection to Utah, likely reflecting the type locality or known distribution. Robber flies in this genus are typically aerial predators that capture other insects in flight.
Saropogon bryanti
Saropogon bryanti is a species of robber fly (family Asilidae) described by Wilcox in 1966. It belongs to the genus Saropogon, a group of predatory flies within the subfamily Dasypogoninae. Like other robber flies, it is presumed to be an aerial predator of other insects, though specific details of its biology remain poorly documented. The species has been recorded from limited observations, with six documented occurrences in iNaturalist as of the source date.
