The wings of the Beautiful Plume (Amblyptilla acanthadactyla: wingspan: 17–23 mm) are long and thin, broadening towards the wing tips.
They are coloured reddish-brown with black triangles near the tips.
The brown legs have some banding and small spurs.
Amblyptilla acanthadactyla may be distinguished by its warm reddish brown colour from the greyish brown of Amblyptilla punctidactyla.
