Nacaduba dyopa (Herrich-Schäffer)

Owl-spotted Blue (Nacaduba dyopa)

The Owl-spotted Blue occurs with at least two subspecies from the Solomon Islands and Vanuatu in Melanesia to western Polynesia, where the nominate race is known from Fiji, Samoa and Tonga.

The species reaches a wingspan of about 1,9 to 2,5 cm. The underwings are greyish brown peppered with numerous white bands, the very large and conspicuous hindwing ocelli are prominently outlined in iridescent blue-green.

The caterpillars feed on the leaves of Dendrolobium umbellatum (L.) Benth., a widespread coastal tree.
