Anacampsis innocuella
(Zeller, 1873)
dark-headed aspen leafroller moth
Anacampsis innocuella is a gelechiid described by Zeller in 1873. The is known for its larval of rolling leaves on plants in the Populus, Salix, and Prunus. are small moths with distinctive ash grey coloration and a pale wavy transverse line on the forewings. The "dark-headed aspen leafroller moth" reflects both its appearance and its association with aspen (Populus).

Identification
Distinguished from similar Anacampsis by the combination of ash grey forewings with a pale wavy transverse line and the dark coloration implied by the . The small size (18–22 mm wingspan) and leaf-rolling larval on Populus, Salix, and Prunus can aid in identification. Specific diagnostic features separating it from require examination of genitalia or detailed wing pattern analysis.
Appearance
have a wingspan of 18–22 mm. Forewings are ash grey with a pale wavy transverse line. The "dark-headed" refers to the darker coloration of the region. Overall coloration is muted and cryptic, typical of many Gelechiidae.
Habitat
Associated with deciduous forests and woodlands containing plants in the Populus, Salix, and Prunus. Larval consists of rolled leaves on these host plants.
Distribution
North America. Recorded from Alabama, British Columbia, Illinois, Indiana, Maine, Mississippi, New York, Nova Scotia, Ohio, Oklahoma, Ontario, Quebec, and Vermont.
Diet
Larvae feed on leaves of Populus, Salix, and Prunus . likely do not feed, as is typical for many gelechiid moths, though this has not been explicitly documented.
Host Associations
- Populus - larval leaves rolled by larvae
- Salix - larval leaves rolled by larvae
- Prunus - larval leaves rolled by larvae
Life Cycle
Larvae are leafrollers, constructing shelters by rolling leaves of plants. Specific details of , pupal, and longevity have not been documented in available sources.
Behavior
Larvae roll leaves of plants to create shelters while feeding. This gives rise to the "leafroller ."
Ecological Role
Herbivore as larvae, feeding on leaves of deciduous trees and shrubs. May serve as prey for and other natural enemies; specific ecological interactions have not been documented.
Human Relevance
Minor potential relevance as a defoliator of ornamental or timber Populus and Prunus , though not documented as a significant pest.
