6–9 mm (0.24–0.35 in)
The thoracic pile of the insect is completely white, while the fore and mid femurs are orange in color. On the apical part of the fore femurs, there is a row of 9-12 strong, straight, black posterior setae, which are approximately twice as long as the diameter of the femur; this row ends in a single longer seta with a strongly curved apex at the apex of the row. Additionally, there is a row of 3-5 strong yellow ventral setae on the basal third of the fore femur, and these setae are slightly shorter than the femoral diameter. On the basal third of the mid femur, there is a row of 2-5 long strong, yellow or black anteroventral setae, and the longest of these setae is approximately twice the femoral diameter. The wings are mostly bare on the basal half. The spots of the tergites are orange, dull yellow, or entirely grey, and they are always overlaid with strong silvery pollinosity. [4]
Spilomyia sayi, the Four-lined Hornet Fly, is a fairly common species of syrphid fly. This species is found from western Canada to 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. The larvae are known as the short-tailed larvae, suited for moist areas such as rot holes of trees. It is a wasp mimic.
Platycheirus clypeatus is a species of hoverfly. It is found across the Palearctic and in the Nearctic. The larvae feed on aphids. Adults are usually found on the edges of woodland or scrub, heath or along hedgerows where they visit a wide range of flowers.
Platycheirus is a large genus of hoverflies. They are also called sedgesitters.
Platycheirus granditarsus, the Hornhand Sedgesitter, is a species of hoverfly. It is found in many parts of Britain North America and Europe. Typical habitat includes marshy meadows and ditches, where it can be found between May and October, though it is at its commonest between July and September. The most distinctive feature of this fly is the red-orange abdomen most easily seen as it takes off or alights.
Platycheirus angustatus is a species of hoverfly. It is found in many parts of the Palearctic, and in the Nearctic.
Platycheirus discimanus, the Yellowfoot Sedgesitter is a small species of hoverfly. It is found across Europe and the Palearctic and in North America.
Platycheirus immarginatus, the Comb-legged Sedgesitter, is a common species of hoverfly. It is found in parts of northern Europe and northern North America.
Platycheirus perpallidus is a species of hoverfly. It is a Holarctic species.
Zigrasimecia is an extinct genus of ants which existed in the Cretaceous period approximately 98 million years ago. The first specimens were collected from Burmese amber in Kachin State, 100 kilometres (62 mi) west of Myitkyina town in Myanmar. In 2013, palaeoentomologists Phillip Barden and David Grimaldi published a paper describing and naming Zigrasimecia tonsora. They described a dealate female with unusual features, notably the highly specialized mandibles. Other features include large ocelli, short scapes, 12 antennomeres, small eyes, and a clypeal margin that has a row of peg-like denticles. The genus Zigrasimecia was originally incertae sedis within Formicidae until a second species, Zigrasimecia ferox, was described in 2014, leading to its placement in the subfamily Sphecomyrminae. Later, it was considered to belong to the distinct subfamily Zigrasimeciinae.
Platycheirus confusus, the Confusing Sedgesitter, is a species of syrphid fly in the family Syrphidae.
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 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.
Palaeopsychops is an extinct genus of lacewing in the moth lacewings family Ithonidae. The genus is known from Early Eocene fossils found in Europe, and North America and is composed of ten species. The ten species can be informally separated into two species groups based on veination of the forewings, the "European" and "North American" groups. When first described, the genus was placed in the family Psychopsidae, but later was moved to Polystoechotidae, which itself is now considered a subgroup of the moth lacewings.
Clambus ceylonicus, is a species of fringe-winged beetle endemic to Sri Lanka.
Sphegina (Asiosphegina) amplistylus is a species of hoverfly in the family Syrphidae found in the Philippines. It's similar to S. inflata, S. philippina, and S. spathigera.
Sphegina (Asiosphegina) atrimanus is a species of hoverfly in the family Syrphidae found in Vietnam.
Sphegina (Asiosphegina) carinata 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 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.
Platycheirus normae, the paddlearm sedgesitter, is a rare species of syrphid fly observed in northeastern North America. 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 are aphid predators.
Sphaerophoria bifurcata, the symmetric globetail, is a species of syrphid fly in the family Syrphidae. The larvae of this genus are predators of aphids and other small hymenoptera. The larvae of this particular species is not known.
