Eunota togata fascinans
(Casey, 1914)
Salt Flat Tiger Beetle
Eunota togata fascinans is a of in the . It is known from salt flat in the southwestern United States and Mexico, where it occupies unvegetated sandy areas near water edges. The subspecies exhibits specific microhabitat preferences that allow coexistence with other tiger beetle through . is triggered by summer monsoonal rains, limiting its active period to a relatively short post-monsoonal season.

Identification
Eunota togata fascinans can be distinguished from by its exclusive association with unvegetated areas near and 10-20 meters from water edges in salt flat . It shares the salt flat environment with other tiger beetles but occupies a distinct microhabitat zone, unlike Cicindela willistoni estancia and Ellipsoptera nevadica which occur strictly along the water's edge, or Cicindela fulgida rumppii which occupies vegetated dry sand areas.
Habitat
Salt flat , specifically unvegetated sandy areas near water edges and 10-20 meters from the water's edge. Occurs in saline environments with damp to dry sand devoid of vegetation.
Distribution
Recorded from New Mexico (Torrance County, Laguna del Perro region), with broader distribution in southwestern United States and Mexico.
Seasonality
activity occurs during the post-monsoonal period in summer, with triggered by summer monsoonal rains. Observed in July in the Laguna del Perro region.
Behavior
Occupies a specific microhabitat zone within salt flat environments, demonstrating partitioning that reduces competition with co-occurring . The appears to be restricted to 1-2 microhabitats within its habitat, showing fidelity to unvegetated sandy zones.
Ecological Role
Participates in within in salt flat , contributing to coexistence through microhabitat specialization. Likely functions as a of small in its specific zone.

- Ellipsoptera nevadicaShares salt flat but is exclusive to the water's edge, not the unvegetated zones preferred by E. t. fascinans
- Cicindela fulgida rumppiiOccurs in salt flat vicinity but exclusively in vegetated dry sand areas, contrasting with the unvegetated of E. t. fascinans
