Schinia diffusa
Smith, 1891
Schinia diffusa is a small described by Smith in 1891. The species is characterized by a wingspan of 23–28 mm and is known to occur in North America, with confirmed records from Colorado and Texas. feed specifically on Machaeranthera annua, an asteraceous . Like other members of the Schinia, are likely associated with the flowers of their larval plants.

Identification
The can be distinguished from other Schinia by its specific association (Machaeranthera annua) and geographic distribution. Within the , identification to species level typically requires examination of or reference to host plant specificity. The small size (23–28 mm wingspan) and diffuse patterning implied by the species epithet may aid in field recognition, though confirmation requires expert determination.

Appearance
have a wingspan of 23–28 mm. As with many Schinia , adults are likely colorful and patterned to match their flowers, though specific coloration details are not documented in available sources.
Habitat
Associated with supporting the larval Machaeranthera annua, which occurs in open, disturbed areas including prairies, roadsides, and dry grasslands in the southwestern United States.
Distribution
North America, with confirmed records from Colorado and Texas. The likely occurs more broadly in the south-central and southwestern United States where suitable exist.
Diet
feed on Machaeranthera annua ( tansyaster). feeding habits are not documented but are likely nectar from flowers, consistent with other Schinia .
Host Associations
- Machaeranthera annua - larval sole documented ; feed on flowers and developing seeds
Behavior
are likely or flower visitors, as is typical for the Schinia. Males and females probably meet on flowers for mating.
Ecological Role
As a , likely influence seed production of Machaeranthera annua. may contribute to of flowers while feeding on nectar.
