Yponomeuta multipunctella
Clemens, 1860
American Ermine Moth
Yponomeuta multipunctella, commonly known as the , is a small in the . It belongs to a noted for that construct communal webs on plants. The is recorded from the northeastern United States, particularly Vermont. As a member of the Yponomeuta genus, it shares behavioral traits with related species, including -to-light that has been demonstrated to vary under selection pressure from artificial light pollution.

Distribution
Recorded from Vermont, United States. Distribution appears restricted to the northeastern United States based on available occurrence data.
Host Associations
- Prunus - -level association inferred from known Yponomeuta relationships; specific host records for Y. multipunctella not confirmed
Behavior
-to-light has been documented in ; related Yponomeuta cagnagella shows reduced attraction to light in from light-polluted urban areas, with females less attracted than males. This suggests potential for similar behavioral plasticity in Y. multipunctella, though not directly tested.

Light pollution research context
While the provided context describes research on Yponomeuta cagnagella, not Y. multipunctella, the findings demonstrate that Yponomeuta can evolve reduced -to-light under urban light pollution. This establishes a plausible mechanism for behavioral variation in Y. multipunctella where it occurs in light-polluted areas.
