Habitat
Wet and dry lowland forests; also found in cultivated Annona orchards and growing areas at elevations ranging from 40 to 2119 meters in Mexico.
Distribution
Southern Texas throughout Central America to southern Brazil. In Mexico, previously recorded from 12 states with additional records from Morelos, Guerrero, and Puebla. Also documented from Parque Nacional Natural Serranía de Chiribiquete (PNNSCh) in Colombia.
Seasonality
Occurs throughout the year, with records from January to November in Mexico. Year-round activity is associated with continuous fruit production of some Annona .
Diet
Larvae feed on fruit pulp of Annona , specifically Annona diversifolia (ilama), Annona reticulata (bullock ), and Annona globiflora. Larvae feed under necrotic tissue on the fruit pulp. diet not specified in available sources.
Host Associations
- Annona diversifolia - larval plantilama; fruit damaged by larval boring
- Annona reticulata - larval plantbullock ; fruit damaged by larval boring
- Annona globiflora - larval plant
Life Cycle
are laid on fruits. Larvae feed on fruit pulp under necrotic tissue, with 1-5 larvae per fruit. occurs on the external surface of the fruit. emerge from pupae. Specific duration of developmental stages not documented.
Behavior
Larvae exhibit fruit-boring , causing on Annona fruits. The is considered a main pest of Annona crops, causing economically important damage alongside Bephratelloides cubensis and Cerconota anonella.
Ecological Role
Pest insect of Annona fruit crops in its native range. One of the primary fruit borers causing economically significant damage to Annona .
Human Relevance
Agricultural pest of economically important Annona fruit crops. Damage caused by larval feeding on fruit pulp results in crop losses. No other documented human interactions.

Taxonomic note
The name Oenomaus is derived from Greek mythology (Οἰνόμαος, 'wine man'), but this etymological origin has no biological significance for the genus.
