Hellula phidilealis
Walker, 1859
Cabbage Budworm Moth
Hellula phidilealis is a small crambid , commonly known as the cabbage budworm moth, whose larvae are specialized pests of cruciferous crops. The occurs throughout tropical and subtropical regions of the Americas, from the southern United States through the Caribbean and Central America to northern South America. Its association with Brassica crops makes it economically significant in agricultural systems.

Identification
Small size (wingspan ~15 mm) distinguishes it from larger crambid . Confirmed identification requires examination of genitalia or association with cruciferous plants in regions where it occurs. Similar small crambids in the same may require dissection for definitive separation.

Appearance
wingspan approximately 15 mm. General appearance typical of small crambid ; specific coloration and pattern details not documented in available sources.
Habitat
Agricultural areas cultivating cruciferous crops; tropical and subtropical environments where Brassicaceae are grown.
Distribution
Tropical and subtropical America: southern United States (Florida to Arizona, north to North Carolina on the east coast), southwestern Mexico, Central America, northern South America (Argentina, Brazil, British Guiana, Paraguay, Peru, Surinam, Venezuela), and Caribbean islands including Jamaica and Barbados. Also recorded from Sierra Leone, Africa, and Hawaii (introduced).
Diet
Larvae feed on cruciferous plants (Brassicaceae), including Brassica oleracea (cabbage) and other brassica crops.
Host Associations
- Brassica oleracea - larval cabbage
- Brassica spp. - larval other brassicas
- other crucifers - larval additional Brassicaceae
Ecological Role
Agricultural pest on cruciferous crops; larval feeding damages cabbage and related brassicas.
Human Relevance
Economic pest of cabbage and other brassica crops in tropical and subtropical agricultural regions.

More Details
Taxonomic note
placement has shifted historically; some older literature refers to Pyralidae rather than Crambidae, reflecting revised classification of this group.
Distribution expansion
Records from Hawaii and Sierra Leone suggest human-mediated or previously undocumented range, though these may represent introductions rather than native occurrence.
