Amannus vittiger

Arid and semi-arid environments of the southwestern United States, including roadside vegetation in desert and semi-desert landscapes. Observed in association with sandy soils and open areas where host flowers bloom.

Southwestern United States. Documented from northeastern Arizona (Coconino County), southern Utah (Kane County), and northwestern New Mexico. Distribution records from GBIF confirm presence in the United States.

Adults active in early to mid-June based on field observations from 2025. Activity coincides with blooming period of globemallow flowers (Sphaeralcea spp.).

Adults have been observed visiting flowers of Sphaeralcea coccinea (scarlet globemallow) and Sphaeralcea parvifolia (small-leaved globemallow), suggesting nectar or pollen feeding. Larval diet unknown.

• Sphaeralcea coccinea - flower visitationAdults collected from flowers in Utah and Arizona
• Sphaeralcea parvifolia - flower visitationAdult collected from flowers in Arizona

Adults are diurnal flower visitors. Multiple individuals have been observed together on the same flower patch, suggesting aggregation at blooming resources. Readily collected by sweeping flowering vegetation.

• Other Amannus speciesGenus-level similarity in body form and antennal structure; specific distinguishing features for A. vittiger not documented in available sources
• Other TrachyderiniTribe members share robust body form and often visit flowers; A. vittiger may be distinguished by specific elytral patterning (implied by specific epithet 'vittiger' meaning 'striped') but detailed comparisons unavailable
