Rivula stepheni

The small size (17 mm wingspan) and southeastern US coastal distribution may help distinguish this species from other Rivula. Positive identification requires examination of genitalia or reference to the original description.

Small moth with a wingspan of approximately 17 mm. Detailed coloration and pattern are not described in available sources.

Associated with grassy and sedge-dominated habitats in the southeastern United States. Specific microhabitat preferences are not documented.

Eastern North Carolina, Louisiana, and Florida, United States.

Adults active from April to September in North Carolina, with peak activity spanning the warm season.

Larvae feed on various grasses and sedges (Poaceae and Cyperaceae). Adult feeding habits are not documented.

• Poaceae - larval host plantvarious grasses
• Cyperaceae - larval host plantvarious sedges

Likely has three to four generations per year based on the extended adult flight period from April to September. Continuous breeding is inferred from this pattern. Specific details of egg, larval, and pupal stages are not documented.

Larval herbivore on grasses and sedges; specific ecosystem functions are not documented.
