To which family does Endrosis sarcitrella belong, and what is a common ancestral food source for relatives?
Answer
Oecophoridae; fungi, lichens, or plant debris.
*Endrosis sarcitrella* is classified within the family Oecophoridae, which is recognized as a large and diverse group of microlepidoptera. While the White-shouldered House Moth has successfully adapted to utilizing stored organic matter provided by human activities, many of its relatives within the Oecophoridae family maintain ancestral feeding habits focused on natural environments. These relatives typically feed on detritus such as fungi, lichens, or fragmented plant debris found outdoors. This contrast highlights the evolutionary shift this specific species made towards stored carbohydrates and starches, moving away from the natural substrates favored by the broader family.
