The dark-edged bee-fly, or 'large bee-fly', looks rather like a bumblebee, with a long, straight proboscis that it uses to feed on nectar from spring flowers, such as primroses and violets. It is on the wing in the early spring, when it can often be seen in sunny patches. In flight, it is even more like a bee as it produces a high-pitched buzz. This species of bee-fly is common, but the heath and mottled bee-flies are much rarer.Sut i'w hadnabod
Looking like a bee, the dark-edged bee-fly has yellowy-brown hair on its body, long, spindly legs, and a long proboscis. The wings have dark markings along their leading edges, hence it's common name. There are several species of bee-fly in the UK, which can be very difficult to tell apart; the dark-edged bee-fly has a dark edge to the wings, while others have plainer, translucent wings.Dosbarthiad

The larvae of the dark-edged bee-fly are nest parasites of ground-nesting and solitary bees, feeding on the bee grubs. The female bee-fly flicks her eggs towards the entrance holes of solitary bee nests to allow the larvae to hatch in the right place. She even coats her eggs with sand, soil, or gravel to protect them, camouflage them, and make them easier to throw!Bee-fly egg flicking (https://vimeo.com/410980790)
