Spragueia perstructana
(Walker, 1865)
Spragueia perstructana is a small noctuid described by Francis Walker in 1865. It is notable for its specialized larval diet on camara, an shrub in many regions. The occurs across a broad geographic range from the southern United States through the Caribbean and into Central America. Its small size and specific association distinguish it within the Spragueia.

Identification
The small wingspan (approximately 15 mm) and association with camara plants may aid identification. Distinguishing features from congeneric are not documented in available sources. Genital dissection or molecular analysis may be required for definitive identification.

Appearance
A small with a wingspan of approximately 15 mm. As a member of the Acontiinae, it likely exhibits the compact body and relatively broad wings typical of the group. Specific coloration and pattern details are not documented in available sources.
Habitat
Associated with areas where the larval plant camara grows, including disturbed , open woodlands, and tropical and subtropical regions. Specific habitat preferences for the stage are not documented.
Distribution
Found in the United States (Maryland, South Carolina, Florida, Texas), south through the Caribbean (Cuba, Puerto Rico, British Virgin Islands), and into Central America ( Rica).
Diet
Larvae feed on camara (Verbenaceae). feeding habits are not documented.
Host Associations
- Lantana camara - larval plantSpecific and documented larval diet; no other plants are recorded
Ecological Role
As a herbivore on camara, larvae may contribute to of this plant in regions where both occur. The extent of this impact has not been quantified.
Human Relevance
Potential value as a biocontrol agent for camara, a significant weed in many tropical and subtropical regions. No other documented human interactions.

Taxonomic history
Originally described as Agrophila perstructana by Walker in 1865, later transferred to the Spragueia.
Biocontrol potential
The specialized feeding on camara suggests potential for biocontrol research, though formal studies on efficacy and safety appear unpublished.
