It is widespread from the Red Sea to India, Myanmar, Sri Lanka, Malaya to Australia and widespread in the Pacific Islands, including the Solomons, New Hebrides, Fiji, Samoa, Hawaii, the Society Islands, Austral Islands, Marquesas and the Marshall Islands.
The wingspan is about 40 mm. It is dark grey brown with a rusty tinge on its body. The abdomen is fuscous. Forewings with sub-basal, antemedial and postmedial double waved lines indistinct. The orbicular small and ochreous, whereas reniform blackish. Submarginal line whitish and irregularly waved. There is a white patch often can be seen between orbicular and reniform and a dark patch on the central marginal area. Hindwings opalescent and semi-hyaline white, with a dark marginal line.
The larvae feed on various grasses, including rice, wheat, Cynodon, Pennisetum clandestinum, Sorghum bicolor, Oryza sativa, and trees such as Casuarina equisetifolia... Wikipedia →

With luck
About 10% of wildlife watchers report a Lawn Armyworm Moth sighting in Harare on a given day, based on 5 verified sightings from GBIF citizen-science data. It is the 76th most-seen of the 93 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.
April
In that month about 20% of wildlife watchers report a Lawn Armyworm Moth in Harare on a given day, against under 5% in June to February, the lowest months. That is one of Harare's driest months, with about 30 mm of rain against 200 mm in December.
Between 8 and 11 pm
Across all the parks we cover, that three-hour window holds the most Lawn Armyworm Moth sightings with a recorded time, and about 9 in 10 of them come between 6 pm and 6 am: it is mostly seen at night.
Among the best
Of the 4 cities where we can rate Lawn Armyworm Moth sightings, Harare ranks 2nd at about 10%, level with the leaders once rounded. The best odds are in Brisbane (Australia, about 10%).
GBIF citizen-science records
It is estimated from how often the Lawn Armyworm Moth is recorded against all the insects logged in Harare (5 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.
