Virginia Creeper Clearwing
Albuna fraxini, commonly known as the Virginia Creeper Clearwing, is a in the . The is to the northern United States and southern Canada. are active during summer months and are notable for their -mimicking appearance.

Identification
Distinguished from other by combination of small size (18 mm wingspan), specific period (June-August), and geographic range. Most similar to other Albuna ; precise identification may require examination of or larval association. The Virginia creeper clearwing can be separated from the related Synanthedon species by subtle differences in and body proportions.

Appearance
Small with wingspan approximately 18 mm. are largely transparent with dark borders, characteristic of the . Body coloration mimics , with and black banding patterns. are relatively long and slender.
Habitat
Associated with deciduous woodlands and forest edges where plants occur. inhabit stems of Virginia creeper and ash trees. are found in areas with flowering vegetation for nectar sources.
Distribution
Northern United States and southern Canada. Specific records include Vermont and broader Nearctic region distribution.
Seasonality
active from June to August. Adult lifespan approximately one week. Single per year inferred from period.
Diet
feed internally on stems of Virginia creeper (Parthenocissus quinquefolia), ash (Fraxinus americana), red ash (Fraxinus pennsylvanica), green ash (Fraxinus pennsylvanica var. subintegerrima), European ash (Fraxinus excelsior), and occasionally mountain-ash (Sorbus ). feeding habits not documented in sources.

Taxonomic History
Originally described as Carmenta fraxini by Edwards in 1881, later transferred to Albuna.
Conservation Status
Not formally assessed; appears secure based on wide distribution and use within ash and Virginia creeper.
Research Needs
feeding and precise larval development timing remain undocumented. trends warrant given widespread ash decline from emerald ash borer.
