Which marking is known for covering the whisker bed and upper lip?

The butterfly marking is specifically recognized for its distinctive coverage of the whisker bed and upper lip in rabbits. This marking typically appears as a symmetrical shape that resembles a butterfly, with the coloration often contrasting the base fur. The characteristic pattern enhances the facial appearance of the rabbit, making it a notable trait in various breeds.

In contrast, the cap marking generally refers to a distinct coloration on the top of the head, which does not encompass the whisker bed and upper lip. The Charlie marking indicates a particular color pattern that may involve a combination of colors but does not specifically cover the face in the manner described. Lastly, the chain marking relates to a pattern often found on the sides and body, again excluding the area around the whisker bed and upper lip. Thus, the butterfly marking is unique in its specific covering of these facial features.
