About Parthenos tigrina van Vollenhoven, 1866
The nominotypical subspecies Parthenos tigrina tigrina has forewings with white spots that carry a yellowish tint, and its wing bases are a deep brownish-yellow. The underside of its wings is yellowish-green, marked with clear black submarginal bands. This taxon was originally described from a specimen collected at Salawati, and it matches closely with specimens from Aetna and Kajumera Bay, located in modern-day Indonesia. Records of specimens from Geelvink Bay further confirm this region as part of its distribution. Several closely related forms are recognized within this species group. One related taxon, Parthenos sylvia nodrica, first identified at Dorey, is a darker form that has smaller intramedian spots on its forewings. Parthenos tigrina terentianus, found in the Arfak Mountains, is distinguished in males by forewings that are completely covered in black scales. The larvae of Parthenos tigrina live in large communal groups. They can be told apart from Parthenos sylvia guineensis by their darker dorsal line. Larval coloration is highly variable, ranging from pale to dark forms; all larvae are covered in white bristles and feed on climbing plants. The pupae of Parthenos tigrina are green, shaped like a boat, and have two points at the head. Another subspecies, Parthenos tigrina pardalis, differs from Parthenos tigrina tigrina in having a broader black outer margin on all wings, and smaller white hyaline spots on the forewings. Additional distinguishing features include a reduced number of white costal and subapical spots, and broader black markings along the anal angle of the forewings. The underside of Parthenos tigrina pardalis is noticeably melanistic, with broad black submarginal bands and a heavily marked outer margin; these features are not noted in the original description of Parthenos tigrina tigrina. Parthenos tigrina pardalis has been recorded from Waigeo Island.
