In brief: Becuase it is shaped

Because the rash is shaped angularly like butterfly wings: the torse being the nose and the rash spreading wider across the cheeks.
Many facial rashes can resemble the malar rash of sle. Tests can differentiate!

In brief: Rash location

The rash goes on each cheek and cross the bridge of the nose.
From the visual point of view it looks like the wings of a butterfly. Lupus erythematosus aka red wolf got it names because the facial rash somewhat matches the facial appearance of the red wolf. The red wolf is known "canis lupus rufus". This is some of the background.
