• Acanthopteroctetes unifascia

  Acanthopteroctetes unifascia is a small moth in the family Acanthopteroctetidae, described by Davis in 1978. It is known from Montana, where adults are active in July. The species has been studied for its anatomical features, which retain ancestral traits while also showing unique specializations in larval trunk and adult head structures. These characteristics suggest it represents a transitional form in moth evolution.
