Platycheirus angustatus
This record describes Platycheirus angustatus (species). Recorded family: Syrphidae. Recorded order: Diptera.
Identification and Appearance

Our most narrowly-built Platycheirus with males that could be overlooked as Melanostoma mellinum in the field until the broadened front legs are seen. It belongs within the clypeatus group with front legs modified in much the same way as other members of the group, though the tergites are much narrower - tergite 3 is usually 1.5 times as long as broad. The male tarsi have distinct dark markings beneath unlike clypeatus and occultus . Separation from europaeus is most difficult. Female angustatus generally have the abdomen very narrow and tapering at the tip, and the spots on tergite 4 often missing. Like the male, the sides of the thorax are brightly shining, much more so than other members of the clypeatus complex. P. europaeus is most similar species but is larger with a slightly broader build, more heavily dusted thorax sides, slightly different markings beneath the male front tarsi and a broader alula on the wings. Unless identified by a recognised expert, a photo is required and the specimen should be examined with a microscope. In the comments box, state the key or ID method used and describe the size and identifying characters. Found in a variety of grassy habitats and wetlands. The larvae are aphidophagous in low vegetation, including Winter Wheat. This is a widespread and locally common species in Britain. No additional images available for this species.

About Flies: the wider group
Order-level background for Diptera, the group containing Platycheirus angustatus. Species-specific details appear above.
Group overview
Diptera includes over 150,000 described species of flies, mosquitoes, and midges. Mosquitoes are the deadliest animal on Earth (CDC). Malaria alone causes ~249 million cases and over 608,000 deaths annually, mostly children under 5 (WHO). Vector-borne diseases account for over 17% of all infectious diseases, causing 700,000+ deaths per year.
Ecological role of the group
Despite their disease impact, flies are critical decomposers and pollinators. Hoverflies alone pollinate hundreds of crop and wildflower species. Flies are also the primary food source for many birds, bats, and fish. Forensic entomology relies heavily on fly species for crime scene analysis.
Economic and practical significance of the group
In the U.S., vector-borne disease cases tripled between 2004-2016, with over 640,000 cases reported in that period (CDC). Tickborne diseases doubled from 22,000 to 48,000 annual reports. Globally, mosquito-borne diseases cost billions in healthcare and lost productivity.
Recorded sources for this group: WHO, CDC, PNAS. Imported estimates may describe particular regions or reporting periods.
