Grown-up dark widow arachnids have a sparkly, dark, adjusted, roundabout mid-region and are around 1/3 inch long (around 1-1/2 inches when their legs are spread).

They are normally perceived as a result of their red or red-orange hourglass structure on the base of their mid-region. This design is alterable and may look like two isolated spots.
