Caloptilia canadensisella
(McDunnough, 1956)
Caloptilia canadensisella is a leaf-mining in the Gracillariidae. It is known from eastern Canada, specifically Nova Scotia and Québec. The larvae feed on Cornus canadensis (bunchberry), creating mines in the leaves of this plant. The was described by James Halliday McDunnough in 1956.

Identification
As a member of the Caloptilia, this likely exhibits the characteristic resting posture with wings held roof-like over the body, giving a slender, elongate silhouette. Species-level identification requires examination of genitalia or detailed wing pattern analysis; the specific epithet references its Canadian distribution. It can be distinguished from other Caloptilia species by association with its plant Cornus canadensis and confirmed through dissection or .
