The wingspan is about 12 cm, making it exceptionally large for an Erebidae species. The larvae feed on Acacia and Entada species.
Its wingspan is about 134–160 mm. Male with costal half of hindwing aborted to form turned over on the upper surface and containing a large glandular patch of flocculent (woolly) hair. Vein 4 running to the functional apex, and vein 5 from center of discocellulars. Vein 6 to the fold and veins 7 and 8 very minute to near base of costa. fuscous brown, with a slight purplish tinge. Forewings with short sub-basal and waved antemedial and medial black lines. A very large fulvous ocellus found beyond end of cell, with black outline and black comma-shaped pupil with blue streaks and specks on it. Two irregularly waved postmedial lines excurved round the ocellus and bent inwards below it, the outer one expanding into a patch at costa. Two sinuous series of black sub-marginal spots, the inner series indistinct and obsolete towards costa. Hindwings with medial black line... Wikipedia →

Rare
Under 5% of wildlife watchers report a Common Owl Moth sighting in Bangkok on a given day, based on 15 verified sightings from GBIF citizen-science data. It is the 113th most-seen of the 245 insects we can rate there. Over three days the chance rises to about 10%, and over a week to about 30%, if each day is a fresh chance.
February and May–June
In those months about 10% of wildlife watchers report a Common Owl Moth in Bangkok on a given day, against under 5% in March–April and July–January, the lowest months.
Between 8 and 11 pm
Across all the parks we cover, that three-hour window holds the most Common Owl Moth sightings with a recorded time, and about 6 in 10 of them come between 6 pm and 6 am: it is seen both by day and at night.
5th of 7
Of the 7 cities where we can rate Common Owl Moth sightings, Bangkok ranks 5th at under 5%. The best odds are in Bengaluru (India, about 10%), Nashik (India, about 10%) and Pune (India, about 10%).
GBIF citizen-science records
It is estimated from how often the Common Owl Moth is recorded against all the insects logged in Bangkok (15 verified sightings), 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.
