In 3 days ~10% in a week ~30%
Macdunnoughia confusa, or Dewick’s plusia, is a moth of the family Noctuidae. It was first described by James Francis Stephens in 1850. It is found from Europe through Siberia to Japan and is also present in Lebanon and Israel.
The wingspan is 30–38 millimetres (1.2–1.5 in). The length of the forewings is 12–17 millimetres (0.47–0.67 in). The moth flies in three generations from April to October [1]. The larvae feed on various herbaceous plants such as Lamium, nettle, Artemisia absinthium and chamomile. Wikipedia →

With luck
About 10% of wildlife watchers report a Dewick's Plusia sighting in Beijing on a given day, based on 20 verified sightings from GBIF citizen-science data. It is the 139th most-seen of the 401 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.
April, June–July and September
In those months about 10% of wildlife watchers report a Dewick's Plusia in Beijing on a given day, against under 5% in May, August and October–March, the lowest months. Those are among Beijing's wettest months, with about 80 mm of rain a month against almost none in January.
Between 11 pm and 2 am
Across all the parks we cover, that three-hour window holds the most Dewick's Plusia 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.
Among the best
Of the 15 cities where we can rate Dewick's Plusia sightings, Beijing ranks 7th at about 10%, level with the leaders once rounded. The best odds are in Kharkiv (Ukraine, about 10%), Porto (Portugal, about 10%) and Kyiv (Ukraine, about 10%).
GBIF citizen-science records
It is estimated from how often the Dewick's Plusia is recorded against all the insects logged in Beijing (20 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.
