Habitat

have been documented in arid highlands of the western Andes slopes, transverse valleys of the Atacama Desert, and other South environments. The occupies a range of across the Americas, though specific habitat preferences vary by species.

Distribution

Documented from North, Central, and South America. Specific records include: northern Chile (A. jobimi, A. azapensis, A. coquimboae), Argentina, Ecuador, and Peru (A. excreta). The discovery of A. jobimi filled a significant distribution gap in mainland South America west of the Andes Range.

Diet

of multiple feed on Asteraceae. A. jobimi and A. azapensis larvae are florivorous, feeding on of Baccharis alnifolia and Pluchea chingoyo respectively. A. primulacea and A. microdactyla larvae induce stem on Chromolaena odorata and Eupatorium cannabinum. feeding habits are not documented.

More Details

Taxonomic uncertainty

Mitochondrial analysis of A. azapensis and A. jobimi supports their placement in Adaina but indicates that the current generic circumscription may need re-evaluation. The contains approximately 42 described as of 2023.

Distribution gaps

The discovery of A. jobimi in 2020 represented the first record of the west of the Andes Range in mainland South America, highlighting that Adaina diversity in underexplored regions remains incompletely documented.
