Aspilanta viticordifoliella

Distinguished from other Aspilanta species by the absence of an apical spot on the forewings. Differentiated from Antispila species by white-tipped antennae. The combination of reduced wing venation, specific silvery marking pattern, and Vitaceae host association confirms identification.

Associated with habitats supporting its Vitaceae host plants: Virginia creeper, false Virginia creeper, and frost grape. These include woodland edges, forest openings, and riparian areas in eastern North America.

Eastern North America. Recorded from Canada (Ontario, Québec) and United States (Connecticut, Florida, Kentucky, Massachusetts, New York, Pennsylvania, Vermont).

Adults active during warmer months; larvae present when host foliage is available. Pupal cases overwinter, with emergence following cold stratification from October/November through February/April.

Larval leaf mining on Vitaceae: Virginia creeper (Parthenocissus quinquefolia), false Virginia creeper (Parthenocissus vitacea), and frost grape (Vitis vulpina).

Egg deposited on host leaf. Larva mines leaf tissue, creating a compact blotch mine sometimes preceded by a short linear portion. Mature larva cuts a 3.5–4 mm elliptical case from the leaf, exits through the resulting hole, and pupates within the case. Overwinters as pupal case with cold stratification required for emergence.

Larval mining behavior produces distinctive leaf mines with black frass in a thick clump near the mine beginning, becoming more dispersed toward the center. Mature larva excises a precise case from the leaf for pupation, leaving a clean elliptical hole.

Herbivore on native Vitaceae; leafmining activity creates minor damage to host foliage. Serves as host for parasitoid wasps including Chalcidoidea and Braconidae (Microgastrinae).

Minor economic interest as a native herbivore on grape relatives; no significant pest status reported. Contributes to biodiversity documentation and understanding of leafminer-plant associations.
