Palpada megafemur is a species of flower flies. [1] It is named after its particularly large metafemur. It is found in Brazil.
The following description is of a male specimen. Its face is black except for a brownish tubercle. Its thorax is black except for the yellow scutellum; the postpronotum is yellowish brown; the mesonotum is yellow pilose; the scutellum is yellow except narrowly black on the base; pleuron is gray pollinose; the calypter, plumula and haltere are orange.
Its coxae and trochanters are black; its femora are black except becoming brownish to orange on the apical 1/4, and shiny except for the mesofemur, which is sparsely gray on its apical 2/3; tibiae are orange; tarsi are orange. Its metafemur is greatly enlarged, its ventral margin sinuate, with a large ventral tubercle on the basoposterior 1/3.
The wings are light brown and microtrichose except for some bare portions.
The abdomen's 1st tergum is black; 2nd tergum yellow except for small basomedial triangular maculae; 3rd tergum is yellow, with indistinct dark medial vitta; 4th tergum is brownish black and light yellowish brown laterally. Its 1st sternum is black; 2nd and 3rd sterna are yellow; 4th sternum is brownish black except for its yellow apical margin. Male genitalia are orangish brown. [1]
Toxomerus marginatus, also known as the margined calligrapher fly, is a common species of hoverfly. It is found in many parts of North America.
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.
Eupeodes rojasi is a species of hoverfly. It is named after Sergio Rojas, the administrator of the Subestación Experimental La Cruz (Chile). It feeds on Eriosoma lanigerum and is found in western South America.
Macrometopia maculipennis is a species of hoverfly, from the family Syrphidae, in the order Diptera. It was first found in Colombia, and was named after its patterned wings.
Orthonevra chilensis is a species of hoverfly first found in Chile.
Palpada lindneri is a species of flower flies first found in Bolivia. Palpada lindneri is easily distinguished from all neotropical Palpada species by its abdominal pattern.
Palpada suprarufa is a species of flower flies first found in Ecuador. It is named suprarufa, based on the appearance of the species.
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.
Palpada vinetorum is a species of syrphid fly in the family Syrphidae. It is a native flower fly species to North America, mainly found in Texas and parts of the east coast.
Helophilus fasciatus, the narrow-headed marsh fly, is an abundant species of syrphid fly observed throughout the United States and Canada. 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 adults of this species lays eggs on vegetation overhanging the water. The larvae hatch and drop into the water.
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.
Eristalis bellardii, the Mexican mountain drone fly, is an uncommon species of syrphid fly first officially described by Jaennicke in 1867. It is infrequently found in the Southwestern United States, Mexico and Central America. In appearance it is somewhat like that of a honeybee. 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.
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.
Sphegina (Asiosphegina) atricolor is a species of hoverfly in the family Syrphidae found in Myanmar.
Sphegina crucivena is a species of hoverfly in the family Syrphidae found in Kambaiti Pass, Myanmar, a montane forest with swampy areas and streams located 2000 meters above sea level.
Sphegina cultrigera is a species of hoverfly in the family Syrphidae found in Kambaiti Pass, Myanmar, a montane forest with swampy areas and streams located 2000 meters above sea level.
Meromacrus gloriosus, the Glorious Elegant, is a species of syrphid fly in the family Syrphidae. Originally described from Mexico by Frank Hull in 1941 this black and yellow wasp mimic has since been observed in many locations in Texas and New Mexico.
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.
Sphiximorpha willistoni, or Williston's wasp fly, is a rare species of syrphid fly found in eastern North America. It is a strong wasp mimic. 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. Larvae in this genus are found in sap runs of trees.
Microdon abstrusus, the hidden ant fly, is a rare and local species of syrphid fly observed in central Pennsylvania. Hoverflies can remain nearly motionless in flight. The adults are also known as flower flies for they are commonly found on flowers though microdon species are seldom seen around flowers. Larvae have been noted in Formica exsectoides ant nests.
