Comfrey Ermel

<em>Ethmia quadrillella</em>, commonly known as the Comfrey Ermel, is a small moth species belonging to the family Depressariidae. This species is now considered Extinct, with historical populations recorded across parts of northern and western Europe, including Belgium, Denmark, Norway, and Sweden. It was associated with open and semi-open habitats where its larval host plants, particularly species of comfrey (Symphytum), once grew. The Comfrey Ermel typically inhabited lowland environments near riverbanks, hedgerows, and disturbed ground where its herbaceous host plants thrived. The dramatic decline and eventual extinction of this species is attributed to habitat loss, agricultural intensification, and the disappearance of suitable host plant communities across its former range. Precise data on its lifespan, body size, and behavioral characteristics remain limited, as the species disappeared before comprehensive biological studies could be conducted. Biological traits of this species remain poorly documented in the scientific literature.
