Schinia erosa

Smith, 1906

Schinia erosa is a noctuid described by Smith in 1906. It inhabits desert regions of the southwestern United States, specifically the Mojave and Sonoran Desert areas east of the Peninsular Range in southern California and south-central Arizona. The is with active in late summer and fall, and exhibits a specialized larval association with Isocoma acredenia (burrobrush), a desert shrub in the Asteraceae .

Distribution

to southwestern North America. Documented from desert areas east of the Peninsular Range in southern California (including the Mojave Desert) and south-central Arizona.

Seasonality

are on wing from late summer to early November, with peak activity likely occurring in September and October.

Diet

Larvae feed exclusively on Isocoma acredenia (burrobrush), a desert shrub. feeding habits are not documented.

Host Associations

Isocoma acredenia - larval Larvae feed on this desert shrub; the specific epithet 'acredenia' refers to this association

Life Cycle

Complete with , larval, pupal, and stages. Larval development occurs on Isocoma acredenia. likely occurs in soil. with one per year.

Ecological Role

As a herbivore, larvae contribute to nutrient cycling in desert through consumption of Isocoma acredenia. The is part of the noctuid guild that provides food resources for including bats and nocturnal birds.

Taxonomic History

Schinia erosa was described by Smith in 1906 and is part of the 'tertia ' within Schinia, a group of closely related that has undergone taxonomic revision. The species epithet 'erosa' refers to the eroded or worn appearance of wing markings.

Conservation Status

Not formally assessed. Given its restricted distribution in rapidly urbanizing southern California desert regions and specialized plant association, the may be vulnerable to loss, though no studies have been conducted.
