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

All four British Brachyopa species have an orange/brown abdomen and grey thorax (note that the thorax has no bristly hairs as some flies do). Brachyopa scutellaris and Brachyopa pilosa can be separated from the other two Brachyopa species as the scutellum is orange with no grey dusting at the front edge. However these two species cannot be further separated however without detailed examination. Larvae of Brachyopa species live in sap runs or in decaying sap under the bark of fallen trees. Adults can often be found hovering very near to their breeding sites but they also visit flowers, particularly Hawthorn and Apple. Brachyopa scutellaris is the most widespread species of the genus and is to be found throughout England and into Scotland and Wales, but by far the most records come from the extreme south of England. Brachyopa pilosa is far less common and records are concentrated around the London area. No additional images available for this species.

About Flies: the wider group
Order-level background for Diptera, the group containing Brachyopa scutellaris. 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.
