Tropical Fritillary

Fascinating facts about the Tropical Fritillary

• The Indian fritillary stretches its wings to a span of 80-98 mm (3.1-3.9 in). Its forewings blaze with rich orange-yellow, while the hindwings carry a paler yellow base edged with intricate black markings that form sinuous lines and spots. The underside flips to a pale terracotta red that deepens toward the apex, adding a subtle gradient of colour.
• In January 2020, the Indian fritillary was recorded for the first time in the United Arab Emirates, spotted in Wadi Wurayah National Park among the Hajar Mountains. Researchers think the butterflies arrived as opportunistic migrants, drawn by the unusually wet conditions after heavy rains that began in October 2019.
• The Indian fritillary's range stretches from the outer Himalayas, spanning Punjab to Sikkim, through the Indian subcontinent, into Southeast Asia, China, Taiwan, and as far south as Java and Sumatra, even reaching southern Japan. In Australia, it is limited to northern New South Wales and southern Queensland.
• Scientists recognise eleven subspecies of Argynnis hyperbius, each tied to a specific region, from A. h. hyperbius across central India to China, to A. h. taprobana in Sri Lanka, and A. h. neumanni in Ethiopia. These geographic variants display subtle shifts in wing colour and pattern.
• The caterpillar of the Indian fritillary is a striking black canvas splashed with orange-tawny markings and a wide dorsal stripe, while its head bears four straight horizontal black spines. Its body segments sport pink spines tipped in black, giving the larva a vivid, almost armored appearance.
