Hadromyia aldrichi is a species of hoverfly in the family Syrphidae. [2]
"Very similar to opacus but more robust, head obviously broader than high; abdomen brilliant bronze, with the pile more golden. "
"Female: Frons depressed, dull aeneous black, somewhat reddish above antennae, with dark brown pile and very narrow whitish pollinose stripes along eyes. Dorsum of thorax sub-shining black, with dark brown pile; meso-pleurae with rather long golden pile; posterior margin of scutellum and post-alar calli with yellow pile. Abdomen banded similarly to opacus. Fore femora dark on outer side, yellow on inner side; middle femora al- most entirely yellow; hind femora yellow, a dark band around the middle; the rest of legs yellow, except the last two joints of all the tarsi. Wings infuscated anteriorly, darkest along the veins. Length: Body about 12–14 mm., wing 11–12 mm. " from original description [1]
The male genitalia were figured by Metcalf. [3]
Eristalis cryptarum is a holarctic species of hoverfly. Known as the bog hoverfly or bog-dwelling drone fly, it is a bog specialist but may occur in other wetlands. Its larvae are assumed to live in peat that is saturated with water, such as that found in these boggy areas. The female has been observed depositing eggs on and close to very fresh cow dung along oligotrophic seepages in moorland.
Toxomerus politus, commonly known as the maize calligrapher, is a species of hoverfly. It is known from North, Central and South America. Although little is known about the early stages of this species, associations with corn have been noted. The adults and likely the larvae feed on the pollen of the corn plants.
Eristalis flavipes, the orange-legged drone fly, is a species of hoverfly native to North America. It flies from early April to mid-October, and occurs in a wide variety of habitats, particularly wetlands. 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 flavescens, The Yellow Sapeater, is a fairly common species of syrphid fly. It has been observed in northeastern 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.flavescens larvae have not been described.
Eristalis transversa, the transverse banded drone fly, is a common species of syrphid fly first officially described by Wiedemann in 1830. 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 rat-tailed type but larvae of this specific species has not been reported.
Blera badia, the Common Wood Fly, is a common species of syrphid fly first officially described by Walker in 1849. 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.
Helophilus lapponicus, the Yellow-margined Marsh Fly, is a common species of syrphid fly observed across northern North America, northern Europe, Greenland and Siberia. Hoverflies can remain nearly motionless in flight. The adults are also known as flower flies for they are commonly found on flowers, from which they get both energy-giving nectar and protein-rich pollen. Though common the larvae of this species are not known but the larvae of other species in this genus are associated with wet decaying organic material, particularly accumulations of decaying vegetation in ponds and mud and are a so called rat-tailed type.
Arctosyrphus willingii, the northern longbeak, is a species of rat-tail maggot fly in the family Syrphidae. This species was formerly a member of the genus Lejops.
'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.
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. 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.daeckei larvae have not been described.
Cynorhinella bella, the Western Longnose, is a species of hoverfly in the family Syrphidae.
Helophilus obscurus , the Obscure Marsh Fly, is a common species of syrphid fly observed throughout Canada and the northern United States and Rocky Mountains. Hoverflies can remain nearly motionless in flight. The adults are also known as flower flies for they are commonly found on flowers, from which they get both energy-giving nectar and protein-rich pollen. The larvae of this genus are associated with wet decaying organic material, particularly accumulations of decaying vegetation in ponds and mud and farmyard manure or silage the larvae of this species are not known.
Palpada albifrons , the White-faced Plushback , is a rare species of syrphid fly observed in from Mexico north-eastward along the coastal areas of the United States. Hoverflies can remain nearly motionless in flight. The adults are also known as flower flies, for they are commonly found on flowers from which they get both energy-giving nectar and protein-rich pollen. The larvae are aquatic.
Blera scitula, the Western Wood Fly, is an uncommon species of syrphid fly first officially described by Williston in 1882. 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 the flowers from which they get both energy-giving nectar and protein-rich pollen. The larvae of Blera are of the rat-tailed type, feeding on exuding sap or in the rot holes of trees.
Eristalis hirta, the black-footed drone fly, is a common Western North American species of syrphid fly, first officially described by Loew in 1866. Hoverflies get their names from the ability to remain nearly motionless while in flight. The adults are also known as flower flies as they are commonly found on and around flowers, from which they get both energy-giving nectar and protein-rich pollen. The larvae are aquatic filter-feeders of the rat-tailed type.
'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.
