In 3 days ~30% in a week ~50%
Spodoptera cilium, known variously as dark mottled willow, lawn caterpillar and grasslawn armyworm, is a noctuid moth found throughout much of sub-Saharan Africa and western, southern, and south-east Asia and several countries in southern and eastern Europe. It is a migrant to northern Europe and has been recorded at least nine times in the United Kingdom.
The larva feeds on Oryza. It is sometimes a pest. Wikipedia →

With luck
About 10% of wildlife watchers report a Dark Mottled Willow sighting in Harare on a given day, based on 8 verified sightings from GBIF citizen-science data. It is the 58th most-seen of the 93 insects we can rate there. Over three days the chance rises to about 30%, 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 Dark Mottled Willow in Harare on a given day, against under 5% in May to December, the lowest months. That is one of Harare's driest months, with about 30 mm of rain against 200 mm in December.
Between 4 and 7 pm
Across all the parks we cover, that three-hour window holds the most Dark Mottled Willow sightings with a recorded time, and about 8 in 10 of them come between 6 pm and 6 am: it is mostly seen at night.
Yes
Of the 6 cities where we can rate Dark Mottled Willow sightings, Harare has the highest daily chance: about 10%. Next come Porto (Portugal, about 10%) and Rome (Italy, about 10%).
GBIF citizen-science records
It is estimated from how often the Dark Mottled Willow is recorded against all the insects logged in Harare (8 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.
