ADULT DESCRIPTION AND VARIATION

Wingspan: 82-116mm. Similar to Rhodoprasina corolla Cadiou & Kitching, 1990, from Thailand, but larger and usually with a silvery sheen to the greenish forewings, which are longer and apically pointed. Hindwing pink area usually restricted to the basal half of the wing, but may extend to the centre (Brechlin, 2005). Foretibia with an apical spine. Antennae not reaching the forewing discal spot; in Rhodoprasina corolla they extend beyond this spot. Underside of abdomen with a strong, dark median line posterior from segment four (rather then the narrow, green line present in Rhodoprasina floralis (Butler, 1876)). Smaller individuals may be missing the normal silvery sheen to the greenish forewings, and may have a bluish tint instead. These may also be shorter and more blunted apically, similar to Rhodoprasina corolla.

ADULT BIOLOGY

A montane species occurring between 1100 and 2500m altitude. Males will come to light in large numbers between 19.00h and 03.00h. This is in distinct contrast to other members of the genus, which appear to fly for only a short period after dusk (Brechlin, 2005). In northern Thailand flies at the beginning of the dry season before the onset of the cold season in late December, when nights become much colder.


FLIGHT-TIME

China: x-xi (Hunan; Fujian; Chongqing); 6.xii (Guangdong).

In Thailand, from October until early December.
