Spectroreta is a monotypic moth genus belonging to subfamily Drepaninae erected by Warren in 1903. Its only species, Spectroreta hyalodisca, was described by George Hampson in 1896. It is found in Sri Lanka, the north-eastern Himalayas, China (Zhejiang, Fujian, Jiangxi, Guangdong, Guangxi), Myanmar, Peninsular Malaysia and on Sumatra, Borneo and the Kei Islands.
The wingspan is about 34 mm. The forewings are red brown, variegated with yellow brown on the apical area and a large irregular hyaline yellow patch in and below the end of the cell on the disc, running out to a point between veins 4 and 5 and with a small spot at its inner edge. There is an oblique dark submarginal line and an oblique shade from the apex, as well as some yellow spots on the margin and some black suffusion near the angle. The hindwings are chestnut, slightly variegated with yellow-brown. There is a medial dark line with a minute yellow-ringed black ocellus beyond the middle and there is some yellow on the margin at the angle. Wikipedia →

With luck
About 10% of wildlife watchers report a Spectroreta hyalodisca sighting in Doi Inthanon National Park on a given day, based on 5 verified sightings from GBIF citizen-science data from 2019 to 2026. It is the 131st most-seen of the 153 insects we can rate there. Over three days the chance rises to about 20%, and over a week to about 50%, if each day is a fresh chance.
August
In that month about 40% of wildlife watchers report a Spectroreta hyalodisca in Doi Inthanon National Park on a given day, against under 5% in March–July and September–January, the lowest months. That is one of Doi Inthanon National Park's wettest months, with about 340 mm of rain against 20 mm in February.
Between noon and 3 pm
Across all the parks we cover, that three-hour window holds the most Spectroreta hyalodisca sightings with a recorded time, and nearly all of them come between 6 am and 6 pm: it is a daytime animal.
Among the best
Of the 2 parks where we can rate Spectroreta hyalodisca sightings, Doi Inthanon National Park ranks 2nd at about 10%, level with the leaders once rounded. The best odds are in Khao Yai National Park (Thailand, about 10%).

GBIF citizen-science records
It is estimated from how often the Spectroreta hyalodisca is recorded against all the insects logged in Doi Inthanon National Park (5 verified sightings from 2019 to 2026), calibrated against known sighting rates. Figures are rounded to the nearest 10% because citizen-science data supports honest approximations, not decimals, and months with records from fewer than five people show "—". How it works.
