Microcrambus copelandi

The small forewing length (6–8.5 mm) distinguishes it from larger Crambidae species. Within Microcrambus, identification to species level requires examination of genitalia or comparison with closely related species such as M. biguttellus and M. elegans, which share similar size ranges and grassland habitats. Geographic distribution may aid identification, as M. copelandi has been recorded from more western and southern localities than some congeners.

Small moth with forewings measuring 6–8.5 mm in length. As a member of Crambinae, it likely exhibits the slender body and narrow wings typical of grass moths, though specific coloration and pattern details are not documented in available sources.

Associated with grass-dominated environments, reflecting larval feeding on Gramineae. Specific habitat preferences are not documented beyond this general association.

Recorded from the United States (Arizona, California, Florida, Ohio, South Carolina, Texas) and Mexico. The distribution spans multiple ecological regions from the southwestern deserts to the southeastern coastal plain.

Adults have been recorded from April through September, with additional records in November. This indicates a primarily warm-season activity pattern with possible bivoltine or multivoltine generations.

Larvae feed on Gramineae (grass family) species. Specific host grass genera or species have not been documented.

As a grass-feeding moth, larvae likely function as primary consumers in grassland ecosystems. Their role in nutrient cycling and as prey for parasitoids and predators has not been specifically studied.
