The wings are hyaline or lightly infuscate.

Blera is primarily a North American genus, though there are 3 species from Europe. The genus is characterized by the following characters:
Chalcosyrphus is a genus of hoverflies in the subfamily Eristalinae. Many species exhibit some degree of mimicry of various sawflies and other hymenopterans and are often brightly coloured or metallic in hue. The adults are similar in structure and behavior to the related genus Xylota but differ in larval morphology. They can be found throughout Europe, Asia, and North America and seem to prefer damper, boggy habitats. The larvae are saproxylic feeders in rotten wood in these habitats.
Sercomyia are large flies with species that are bee mimics both short pile and long pile. Sericomyiine flower flies are common in boreal forests across the Holarctic region and southward at higher elevations into the Oriental and Neotropical regions. Sericomyia species have larvae of the rat-tailed maggot type, often found in ponds rich in decomposing vegetation where they filter out microorganisms as their food
Monoceromyia is a genus of hoverfly. Species in the genus are found in the Afrotropical, Australasian, Neotropical and Oriental regions. They are mimics of wasps and the genus is distinguished by the metapleura being widely separate behind the hind coxae. The elongated frontal base of the antenna is at least as long as the basal segment of the antenna and the second abdominal tergum is longer than wide and constricted.
Chaetostomella vibrissata is a species of tephritid or fruit flies in the genus Chaetostomella of the family Tephritidae.
Chalcosyrphus pleuralis is a species of hoverfly in the family Syrphidae.
Chalcosyrphus longus is a species of hoverfly in the family Syrphidae.
Xylota coquilletti is a species of hoverfly in the family Syrphidae.
Nipponerius is a genus of cactus flies in the family Neriidae.
