Callophrys gryneus castalis
Texas Hairstreak
Callophrys gryneus castalis is a subspecies of juniper hairstreak butterfly in the family Lycaenidae. It has been a subject of taxonomic debate regarding whether it warrants elevation to full species status based on mitochondrial DNA barcode divergence. The subspecies is associated with juniper and cedar habitats in parts of its range. Observations are relatively sparse, with limited documentation of its biology and ecology.
