Platycheirus modestus Ide 1926 [1] | |
Platycheirus modestus , also known as the yellow sedgesitter, is an uncommon species of syrphid fly observed throughout Northern North America. Hoverflies can remain nearly motionless in flight. The adults are also known as flower flies for they are usually found on flowers from which they get both energy-giving nectar and protein-rich pollen. Larvae are aphid predators. [2] [3] [4]
Length: 6.2–7.3 mm (0.24–0.29 in) The face is shining black and covered with dense grey powder, except for the bare tubercle. The legs are mostly pale. The front tibia is broadened from the base to the tip, ending in a pointed rear angle. The first front tarsomere (T1, see general anatomy) is widened posteriorly, slightly narrower than the tip of the tibia, and approximately twice as long as it is wide. The remaining front tarsomeres are slightly narrower than the first. The middle femur, on its apical quarter (see lower leg figure 2), has a row of 6–8 long, weak, black setae that are strongly curved backward. The first rear tarsomere is swollen (see Figure 1,b). The scutum and scutellum are shining black, with yellow powder present laterally (figure a). Long yellow hairs are located near the wings. The wings are entirely microtrichose, meaning they are covered with fine hairs. The tergites (abdominal segments) 2–5 are predominantly yellow. Segment 2 has black lines at the front and rear, along with a dark triangular marking in the middle of the front. Segments 3–5 feature thin dark margins at the rear and dark triangular markings in the middle of the front (see figure 1 a & b). [4]

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 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 inversus, also known as the knobfoot 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.
Platycheirus alpigenus is a rare high mountain species of fly. Platycheirus can remain nearly motionless in flight. 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 unknown for this species but Platycheirus are generally aphid predators.

Platycheirus hesperius, the southern punctate sedgesitter, is a fly in the Syrphidae family. It is a rare species found in the USA from Washington south to southern California. Adult Syrphids are also known as flower flies for they are commonly found on flowers, from which they get nectar and pollen. They are also called hoverflies for the ability to often remain nearly motionless in flight.
