The Dark-Edged Bee Fly (Bombylius major) is an insect in the Bombyliidae family of flies. It is also known as the Large Bee Fly or the Large Humblefly.

The Dark-Edged Bee Fly is the similar size and shape of a Bumblebee (Bombus sp.), but its body is more triangular. It is dark-coloured with a brown hairy thorax and abdomen. It has translucent wings with a dark-brown edge. When it rests, its wings are spread out. Bumblebees have two pairs of wings, but the Dark-Edged Bee Fly has only one pair of wngs. 

Its long, grey proboscis (nose) looks like a stinger or sword on the top of its head. Its proboscis is always straight (like a unicorn horn) because it cannot curl or retract it. Butterflies, for example, can roll up their proboscis. The Dark-Edged Bee Fly has long legs. It has short antennae. Unlike a bee, it does not have a stinger.
