Identification
Auletobius cassandrae can be distinguished from other Auletobius by its association with Comptonia peregrina; plant specificity is a key identification cue in this . The species is small-bodied with the compact, rounded form typical of attelabid weevils, featuring a short, broad rostrum and elbowed .

Habitat
Occurs in where Comptonia peregrina grows, including dry sandy or rocky soils, forest edges, clearings, and recently disturbed areas. Sweetfern thrives in poor, acidic soils and is common in pine-oak barrens, burned-over woodlands, and roadsides in northeastern North America.
Distribution
Recorded from eastern Canada (New Brunswick, Newfoundland, Nova Scotia, Ontario) with presence in North America generally. The distribution corresponds to the range of its plant Comptonia peregrina, which extends from Newfoundland west to Ontario and south to North Carolina.

Life Cycle
Females roll leaves of Comptonia peregrina to form protective chambers (leaf rolls) in which are deposited and larvae develop. This is characteristic of the .
Behavior
Exhibits leaf-rolling : females cut and manipulate plant leaves to create cylindrical or spiral rolls that serve as larval nurseries. The rolls protect developing larvae from desiccation and .
Ecological Role
Functions as a herbivore with limited impact on plant . The leaf-rolling creates temporary microhabitats that may be used by other small after weevil larvae depart.
Human Relevance
