Syrphinae
Guides
Nuntianus
Nuntianus is a genus of hoverflies (family Syrphidae) described by Miranda in 2020. It belongs to the tribe Syrphini, a diverse group of flower-visiting flies. The genus was established relatively recently, and its species are found in the Neotropical region. Members of this genus share morphological characteristics that distinguish them from related syrphine genera, though detailed biological studies remain limited.
Orphnabaccha coerulea
A species of hoverfly in the family Syrphidae, described by Williston in 1891. The genus Orphnabaccha is part of the diverse Syrphinae subfamily, whose members are commonly known as flower flies. Species in this genus are typically associated with tropical and subtropical regions of the Americas.
Pelecinobaccha
A genus of hoverflies in the family Syrphidae, endemic to the Neotropical region. Formerly treated as part of the paraphyletic genus Ocyptamus, it was reinstated as a distinct genus based on phylogenetic evidence. The genus contains four species groups and approximately 49 species, many described in a 2014 revision. Adults are presumably pollinators like other syrphid flies, though specific biological data remain poorly documented.
Syrphus
Common Flower Flies
Syrphus is a genus of hoverflies in the family Syrphidae, characterized by distinctive calypter morphology. The genus is distinguished from other Syrphini by long hairs on the upper surface of the lower lobe of the calypter, a unique diagnostic feature. Adults are common flower visitors and pollinators, while larvae are primarily aphid predators. The genus includes approximately 20 described species distributed across the Holarctic region, with several species occurring in North America and Europe.
Toxomerus
Calligrapher Flies
Toxomerus is a large genus of hoverflies (family Syrphidae) distributed across the Americas, with over 130 described Neotropical species and additional Nearctic endemics. Species are small (typically 6–9 mm), characterized by large eyes with posterior indentation and diagnostic abdominal patterns. Most larvae are predatory on soft-bodied insects, particularly aphids, though at least three species are known pollen-feeders. Adults are pollinivorous, feeding on nectar and pollen from diverse flowering plants. The genus includes notable ecological specialists such as Toxomerus basalis, a kleptoparasite of sundews (Drosera), and several species introduced to the Afrotropics.
