The larvae are rat-tailed type but larvae of this specific species has not been reported.
Syrphus knabi, the Eastern flower Fly, is an uncommon species of syrphid fly observed in the eastern United States and Canada. Syrphid flies are also known as Hover Flies or Flower Flies because the adults are frequently found hovering around flowers from which they feed on nectar and pollen. Adults are 7.2–12.9 mm (0.28–0.51 in) long. The larvae are predators of a variety of aphids in trees.
'Dasysyrphus intrudens' is a placeholder name for a complex of hover fly species that have yet to be properly been divided into individual species. It is found in the Holarctic realm. Though this species actually a complex, it is commonly found in many areas of its range, but yet the larvae of this species were not known to science as of 2012. This may be due to the probable nocturnal habit of these larvae if it is similar to some known larvae of this genus.

Hoverflies get their names from the ability to remain nearly motionless while in flight. The adults are also known as flower flies for they are commonly found around and on flowers, from which they get both energy-giving nectar and protein-rich pollen. The larvae are aquatic filter feeders of the rat-tailed type.
Brachyopa daeckei, the black-tailed sapeater, is a rare species of syrphid fly that has been observed in northeastern North America. Hoverflies get their names from the ability to remain nearly motionless while in flight.

Larvae for this genus are of the rat-tailed type. B.daeckei larvae have not been described.
Blera flukei, the red-cheeked wood fly, is a rare species of syrphid fly first officially described by Curran, 1953 as Cynorhina flukei. Hoverflies get their names from the ability to remain nearly motionless while in flight. The adults are also known as flower flies for they are commonly found around and on flowers, from which they get both energy-giving nectar and protein-rich pollen. The larvae are of the rat-tailed type, feeding on exuding sap or in the rot holes of trees.
'Blera confusa , the confusing wood fly, is a common species of syrphid fly first officially described by Johnson, 1913 Hoverflies get their names from the ability to remain nearly motionless while in flight. The adults are also known as flower flies for they are commonly found around and on flowers, from which they get both energy-giving nectar and protein-rich pollen. The larvae are of the rat-tailed type feeding on exuding sap or in the rot holes of trees.
Blera robusta, the greenish wood fly, is a rare species of syrphid fly first officially described by Curran in 1922. Hoverflies get this name from the ability to remain nearly motionless while in flight. The adults are also known as flower flies, for they are commonly found around and on the flowers from which they get both energy-giving nectar and protein rich pollen. The larvae are of the rat-tailed type, feeding on exuding sap or in the rot holes of trees.
Blera metcalfi, Metcalf's wood fly, is a rare species of syrphid fly first officially described by Curran in 1925 Hoverflies get their name from the ability to remain nearly motionless while in flight. The adults are also known as flower flies for they are commonly found around and on flowers from which they get both energy-giving nectar and protein rich pollen. The larvae are of the rat-tailed type feeding on exuding sap or in the rot holes of trees.
Brachyopa caesariata, the Plain-winged Sapeater, is an uncommon species of syrphid fly. It has been observed in Canada, Alaska and northern United States. Hoverflies get their names from the ability to remain nearly motionless while in flight. The adults are also known as flower flies for they are commonly found around and on flowers, from which they get both energy-giving nectar and protein-rich pollen. Larvae for this genus are of the rat-tailed type. B.caesariata larvae have not been described.
Brachyopa diversa , the Pale-striped Sapeater, is a rare species of syrphid fly. It has been observed in the northeastern part of North America. Hoverflies get their names from the ability to remain nearly motionless while in flight. The adults are also known as flower flies for they are commonly found around and on flowers, from which they get both energy-giving nectar and protein-rich pollen. Larvae for this genus are of the rat-tailed type. B.diversa larvae have not been described.
Sericomyia carolinensis, is a rare species in the family Syrphidae, found in the Southeastern part of the United States. It is distinguished by its all yellow face, single pair of small narrow yellow spots, and yellow pilose scutellum. Adults noted feeding on pear blossoms. The larval stage is unknown but is likely a "rat tailed" type larvae inhabiting nutrient rich waters, typical for the genus Sericomyia.
