Anomoea rufifrons occidentimutabilis
Moldenke, 1970
A of case-bearing leaf beetle in the Chrysomelidae. Described by Moldenke in 1970 from western North American of Anomoea rufifrons. The subspecific epithet "occidentimutabilis" suggests variability in western populations. Like other members of the , are associated with woody vegetation and are case-bearers in the larval stage.

Identification
Distinguished from the nominate A. r. rufifrons and other Anomoea subspecies by subtle differences in coloration and pattern, though specific diagnostic characters require examination of type material. As with all Anomoea, have the typical rounded, convex body form of cryptocephaline leaf beetles with enlarged hind adapted for jumping.
Habitat
Associated with juniper-oak-pinyon woodland and montane coniferous forest based on collection records from the southwestern United States.
Distribution
Western North America. Present in the southwestern United States (New Mexico, Arizona) and potentially adjacent regions of northern Mexico. GBIF records indicate presence in Middle America and North America.
Life Cycle
As with other Cryptocephalinae, larvae are case-bearers that construct protective cases from fecal material and plant debris. Larval development occurs within these cases on host vegetation.
Ecological Role
Herbivorous leaf beetle contributing to nutrient cycling in woodland . Larval case-bearing habit may provide some protection from and desiccation.
